In Oracle, you can use DECODE function to evaluate a list of expressions, and if a value is matched return the corresponding result. InSQLServer, you can use CASE expression that is also supported by Oracle. Note thatNULLvalues in DECODE function and CASE expression are handled differently . ...
DECODE function in Standard Query Language (SQL) is used to add procedural IF – THEN – ELSE like statements to a query. It compares a given expression with each search value one by one and returns a result on the basis of outcomes received from the comparison. A decode function basically...
The DECODE function can be thought of as an inline IF statement. DECODE takes three or more expressions as arguments. Each expression can be a column, a literal, a function, or even a subquery. Let's look at a simple example using DECODE:
Advanced SQL > DECODE Function DECODE is a function in Oracle and is used to provide if-then-else type of logic to SQL. It is not available in MySQL or SQL Server. SyntaxThe syntax for DECODE is: SELECT DECODE ( "column_name", "search_value_1", "result_1", ["search_value_n"...
SQL Server-delimited identifiers sometimes contain characters that are not supported in Windows PowerShell paths. These characters can be specified by encoding their hexadecimal values. 备注 There are two SQL Server PowerShell modules; SqlServer and SQLPS. The SqlServer module is the current P...
Hi team, I am analyzing transaction log records in SQL Server using the fn_dblog function for troubleshooting purposes. I have identified operations like LOP_INSERT_ROWS and LOP_MODIFY_ROW associated with a table containing a VARCHAR column. When I…

oracle中decode函数介绍以及在sqlserver中的实现 decode(条件,值1,返回值1,值2,返回值2,...值n,返回值n,缺省值) 该函数的含义如下: IF 条件=值1 THEN RETURN(翻译值1) ELSIF 条件=值2 THEN RETURN(翻译值2) ... ELSIF 条件=值n THEN RETURN(翻译值n) ELSE RETURN(缺省值) END IF decode(字段或...
其中之一是解析函数(DecodeFunction),它用于将一种值转换为另一种值。在本文中,我们将深入探讨MySQL中的解析函数,并提供代码示例来帮助您更好地理解它的使用。 ## 解析函数概述 解析函数是在MySQL中进行条件转换的一种方法。它接受一个或多个参数,并根据条件将输入...
