They provide a way to handle different scenarios and make decisions within your SQL Server scripts or stored procedures. In dbForge Studio for SQL Server, the result will be displayed in the Messages tab of the Error List: SQL Server IF-THEN statementsĪs mentioned before, IF-THEN statements allow you to execute code blocks according to certain conditions. Since the condition is true, the message ‘ The value is greater than 5.’ is printed after the query is executed. The IF statement checks if it is greater than 5. In this example, the variable is assigned a value of 10. Here is an example that demonstrates the usage of an SQL Server IF statement: DECLARE INT = 10 If the condition evaluates to true, the code block within the BEGIN and END keywords will be executed. In the syntax above, the condition is an expression that evaluates to either true or false. code block to execute if the condition is true The basic syntax of the SQL Server IF statement is simple: IF condition This control-of-flow statement allows you to handle different scenarios and make decisions within your SQL Server scripts or stored procedures. SQL Server IF statement provides a way to execute code blocks based on specific conditions. By utilizing these statements effectively, developers can write more sophisticated and flexible code that can adapt to different scenarios and requirements. Control-of-flow statements provide the ability to make decisions based on conditions, iterate over sets of data, handle errors, and control the flow of program execution. They enable the implementation of conditional logic, looping, and branching, which are essential for designing complex and dynamic queries. Overall, the control-of-flow statements allow developers to have more control over the query execution. It allows you to bypass certain codes within a loop based on specific conditions.
