SQL has several comparison operators. The most simple one is the equal operator. You can compare any data type column using the equal operator. For example: SELECT apple_variety, tons_produced FROM apples WHERE year = 2019 After executing the SQL the database returns the records where the year column is 2019 The two strings '4200' and '4200.0' are not the same: 3. Case-insensitive nature of string comparisons: 4. String comparisons in MySQL are not case sensitive by default: 5. To make a string comparison case sensitive, cast (convert) one of the strings to binary form by using the BINA: 6 In contrast to LIKE, search conditions that contain a simple comparison between a string literal and a DATE, TIME, TIMESTAMP, or TIMESTAMP WITH TIME ZONE value use the date/time data type as the comparison domain. In this case, SQL Anywhere first converts the string literal to a TIMESTAMP value and then uses the necessary portion(s) of that value to perform the comparison. SQL Anywhere follows the ISO 8601 standard for converting TIME, DATE, and TIMESTAMP values, with additional extensions

It's primarily useful if you are writing an ad-hoc query with a small enough table that speed. INSTR() is a string function in standard query language (SQL) which returns the starting position or location of a substring or pattern in the given input string. The INSTR() function is specific to Oracle/PL and MYSQL. However, other SQL database servers like PostgreSQL, SQL server support string functions to determine the location of a substring, but they differ a little bit in syntax. The. The padding directly affects the semantics of WHERE and HAVING clause predicates and other Transact-SQL string comparisons. For example, Transact-SQL considers the strings 'abc' and 'abc ' to be equivalent for most comparison operations. The only exception to this rule is the LIKE predicate SQL: Comparison Operators.

POSIX is a set of comparators for case matches and non equivalency. It is the most powerful way to use Regex in SQL If you want to match a string with any string in a list, you can use the IN operator.

Little SQL Server Tricks: Case-Sensitive String Comparison. 2020-05-26 by Johnny Graber. Running your database with a case-insensitive collation is often a great help. If you search for 'de' you find 'de', 'De', 'dE' and 'DE' as well. However, if you need to make a case-sensitive search, that benefit is now a liability and all the other cases clutter your result. Luckily for us, you can. We could have spent countless hours to optimize their performance for dynamic SQL, but the better option would have been us the CASE expression in the WHERE clause.

'Having' clause in SQL is used for aggregation operations along with 'Where', 'group by' & 'order by' condition statements. It is applied on a table/ database where there is need for filtering aggregate results, and also that allows 'group by' and 'order by' conditions. When the 'having' clause is used in a query, it is expected that the resulting output data set. Most SQL Server installations are installed with the default collation which is case insensitive. Because of this it is difficult to determine the differences of a value in upper case vs. lower case. By using COLLATE clause we can force a different col COLLATE is the T-SQL clause used to define collation. BINARY_CHECKSUM() is a built-in system function used to compare the binary check-sum value. In this article I will show you how to use both the options. In addition to lower case search, I'll show you the upper case search and mixed case search as well.

In such cases, you can use HAVING Clause. WHERE Clause filters the records tuple by tuple while HAVING Clause filters the whole group. A query may have both the clauses. There are ways to convert such a string to a date; Oracle SQL, for example, has the TO_DATE function, which can converts strings representing a wide variety of date formats to standard DATE format data. You could use TO_DATE('19920701', 'yyyymmdd') to convert the string '19920701' to '1992-07-01' in DATE format. You have to be careful, though, when dealing with dates in string.

If you compare a field from (a) with a field from (b), then the comparison will be case sensitive (case sensitivity wins). See chapter 7.2.7 String types of the MySQL Reference Manual and look for the statements on sorting and comparisons By default, Oracle checks content as well as casing, while comparing the two strings in where or like or case statements.

A question that is frequently occurring among my SQL training's participants is:. What's the difference between putting a predicate in the JOIN.ON clause and the WHERE clause?.

  1. The SQL CASE Statement. The CASE statement goes through conditions and returns a value when the first condition is met (like an IF-THEN-ELSE statement). So, once a condition is true, it will stop reading and return the result. If no conditions are true, it returns the value in the ELSE clause
  2. A WHERE clause in SQL specifies that a SQL Data Manipulation Language (DML) statement should only affect rows that meet specified criteria. The criteria are expressed in the form of predicates.
