![]() But there are cases when a dynamic plan is worse than a static one. If the STATIC keyword is missing, the cursor is dynamic and uses a dynamic plan if available. READ_ONLY FORWARD_ONLY cursor can be scrolled only from the first row to the last one. If we run the syntax using this argument LOCAL READ_ONLY FORWARD_ONLY we get the same results. Below we have the results:ġ2 seconds are a lot better that 4 minutes and 47 seconds, but keep in mind the restrictions explained above. Basically, no updates, deletes or inserts made after the cursor was open will be visible in the cursors result set unless we close and reopen the cursor.īe aware of this before using these arguments and check if it matches your needs. A STATIC cursor is read-only and is also referred to as a snapshot cursor because it only works with the data from the time it was opened, meaning that it won’t display any changes made in database on the set of data used by the cursor. ![]() The STATIC keyword makes a temporary copy of the data used by the cursor in tempdb in a temporary table. Also, the cursor can be referenced by a stored procedure, trigger or by a local cursor variable in a batch. After the batch finishes executing, the cursor is automatically deallocated. When we specify LOCAL keyword, the scope of the cursor is local to the batch in which it was created and it is valid only in this scope. There are many arguments we can use in a cursor definition, more on that on this link CURSOR Arguments, but for now let’s focus on what this two words mean. Let’s give our cursor another chance and uncomment the line –LOCAL STATIC. If we had to loop through tables with millions of rows it would last a considerable amount of time and the results would not please us. Our demo tables are relative small containing roughly 1,000 and 500 rows. These operations are repeated until there are no more rows to work with.įinally, CLOSE syntax releases the current result set and removes the locks from the rows used by the cursor, and DEALLOCATE removes cursor reference. Then the second SELECT uses the variable value to get data from. In our example, the cursor sets its position to the first row returned by the first SELECT and fetches the ProductID value that matches WHERE condition in variable. Step two, the retrieval, when it gets the data from that specific row in an operation called the FETCH. Step one, the positioning, when the cursor sets its position to a row from the result set. In the cursor execution, we have two steps. It’s important to mention the chosen syntaxes above are only for demo purposes, and I made no index tuning to speed things up. Let’s start by using a CURSOR, and write the following syntax:Īfter a short coffee break, the query finished executing, returning 833 rows in the time shown below. table, for every product that requires less than a day to manufacture, that is from table. Below, we will show some examples where using a CURSOR creates performance issues and we will see that the same job can be done in many other ways.įor the purpose of this demonstration we will use AdventureWorks2012 database, and let’s say we want to get some data from. There are some cases, when using CURSOR doesn’t make that much of a mess, but generally they should be avoided. But be advised, take this path and trouble may follow. ![]() In T-SQL, a CURSOR is a similar approach, and might be preferred because it follows the same logic. If you possess programming skills, you would probably use a loop like FOR or WHILE to iterate through one item at a time, do something with the data and the job is done. In T-SQL, one way of doing this is using a CURSOR. Sometimes the application logic needs to work with a row at a time rather than the entire result set at once. For example, a SELECT statement returns a set of rows which is called a result set. In relational databases, operations are made on a set of rows.

![]() ![]() Become familiar with the concepts in order to craft the ideal team per the ruleset. Attack Order rules factor into which monsters attack first.Blast and Scattershotwill cause the maximum damage here. Use monsters or summoners with Blastto remove the Divine Shield buff from as many monsters on your enemies team as quickly as possible. Holy Protection: "All monsters gain the divine shield ability which reduces the damage of the first attack received to 0." Enemy monsters must be Stunned before they are able to be Knocked Out. Use a monster with Stunto trigger this ability. Heavy Hitters: "All monsters gain the Knock Out ability." Utilize monsters with Scattershotto spread out your attacks beyond the enemy's tank. Enrageis also useful as if your melee monsters are struck by Blast, the Enrage ability will trigger - increasing their attack damage.įog of War: "All monsters lose the sneak and snipe ability." Use monsters with Reflection Shield to limit the impact of Blastdamage. Consider using a ranged attack monster with Scavengertowards the back of your lineup - Venari Seedsmith or Iza the fanged are two options for this strategy.Įxplosive Weaponry: "All monsters gain the blast ability." Using a monster or summoner with Return Fire will turn this around on your opponent. Be aware that they may do the same to you!Ĭlose Range: "Monsters with ranged attacks are allowed to attack in the first position."īe aware that this makes using ranged attack monsters more attractive, as they can now function as tanks.

Northwest (north of Interstate I-10 and west of Grand Parkway/99).Since it is such a large area, with multiple ZIP Codes and three counties, I like to divide Katy into four areas: The area of Katy is so large that it crosses two counties (Harris and Fort Bend) and multiple ZIP Codes (see below). Note the green portion is what we refer to as “Katy TX” and is covered by Katy ISD and mostly has Katy addresses, but the red portion is what is “incorporated” as the City of Katy.Īlso notice that Katy is “kind of” divided into four quadrants, with Interstate I-10 running east-west and Grand Parkway/99 running north-south. For 1 million dollars Katy bought the right to annex the area desired.” City of Katy (incorporated) Inside Greater Katy Map The developer and city of Katy threatened to build just parking lot on the Houston area depriving Houston of any real property tax value. Most recently this came into play with development of the Katy Mills Mall, which sat mostly within the City of Katy but about half was in the Houston ETJ. This has occurred on several occasions in regards to relatively small tracts of land. Some of this area is actually within the extraterritorial jurisdiction of the City of Houston the city of Katy cannot annex this area without express permission from the City of Houston. However, the “Katy Area” or “Greater Katy Area” usually refers to the entire area covered by the Katy Independent School District and various sources quote the population to be somewhere around 340,000.Īccording to Wikipedia, “Many people confuse Greater Katy Texas with the City of Katy, however there is no city representation or services provided to people outside of the actual city limits of Katy. ![]() It is hard to explain to people because, technically, the incorporated “City of Katy” is only a small area of about 15,000 people. ![]() Katy Texas is a very large area on the west side of Houston TX…where the counties of Fort Bend, Harris, and Waller converge. ![]() Starting with 2018 taxes, the itemize-or-don't-itemize question changed quite a bit, as the Tax Cuts and Jobs Act significantly increased the standard deduction. If you purchased your own health insurance (on an after-tax basis) and you're not self-employed, you can include the premiums you paid in your total medical expenses when you're determining how much you'll be able to claim as an itemized deduction). In general, the criteria are fairly broad - most reasonable expenses can be included, as long as you paid them yourself using after-tax funds.Ī key part of this decision is that you have to itemize your deductions in order to deduct medical expenses (note that if you're self-employed and you purchased your own health insurance, you can deduct the premiums you paid without itemizing your deductions, using Line 29 of Form 1040 Schedule 1. IRS Publication 502 will help you figure out what counts as an eligible medical expense. ![]() ![]() So if your total medical expenses are still $9,500, you'll only be able to deduct $4,5. If your AGI is $50,000, you'll only be able to deduct medical expenses in excess of $5,000 (10% of your AGI). Now let's say you're planning for this year - the numbers will be a little different, since the threshold has changed. That leaves you with $5,750 that you can deduct. You're allowed to deduct your medical expenses that exceed that limit, so you have to subtract $3,750 from your $9,500 total. How much can you deduct? First, you calculate 7.5% of $50,000, which is $3,750. So what does that mean in terms of dollars and cents? Let's say your total medical expenses in 2018 were $9,500 and your AGI was $50,000. For 2019 and beyond, it has returned to 10%. As of 2013 (under the Affordable Care Act), it changed to 10%, but the Tax Cuts and Jobs Act ( H.R.1) temporarily reset the threshold to 7.5% for 20. You can only deduct medical expenses that are more than a certain percentage of your adjusted gross income (AGI).

This means that there’s no server process between the application and the database, resulting in faster operations. It provides them instead with direct read and writes access to the actual database files. Unlike other RDBMSs, SQLite does not require transmission protocols such as TCP/IP when communicating with applications. If you’re looking for a fast and compact database system that doesn’t require many configurations, SQLite should be on the top of your list. SQLite is a popular choice for applications that require embedded databases instead of client-server architecture. SQLiteĪs we can infer from its name, SQLite is a lightweight RDBMS. Now, let’s take a look at the most popular RDBMSs and gauge their benefits. Most RDBMSs adhere to SQL standards, so if you are familiar with this language, there’s a high chance that you can easily learn and adjust to different database systems right away. Generally, RDBMSs requires a special language called structured query language (SQL) for you to query and process data. ![]() Each datum can have one or more attributes, which can be retrieved and processed through queries. In the context of an RDBMS, data is managed in tables-otherwise known as relations. The latter of which has gained the most popularity.ĭBMSs have varying approaches to managing data. DBMSs come in various types, such as Hierarchical DBMS, Network DBMS, Object DBMS, and Relational DBMS. To access the stored data, you’ll need a program called a database management system (DBMS). In the simplest sense, a database is a storage of data. ![]() ![]() Some Background About Database Management Systems Fortunately, we’ve compiled everything you need to know, including their benefits, disadvantages, and their best use cases. In this article, we’ll thoroughly compare & review three of the best RDBMSs-MySQL, SQLite, and PostgreSQL.
