在SQL Server中,可以使用CAST函数将int类型的数据转换为字符串类型的数据。CAST函数是SQL Server的内置函数,用于将一个数据类型转换为另一个数据类型。下面是使用CAST函数进行int转字符串的示例: DECLARE@numINTSET@num=123DECLARE@strVARCHAR(50)SET@str=CAST(@numASVARCHAR(50))SELECT@strASConvertedString 1. 2. ...
-- Create the variables for the current character string position 1. -- and for the character string. 1. DECLARE @position int, @string char(15) 1. -- Initialize the variables. 1. SET @position = 1 1. SET @string = 'Du monde entier' 1. WHILE @position <= DATALENGTH(@string) 1....

SQL-92 中定义的 CAST 函数等效于 ODBC 中定义的 CONVERT 函数。 等效函数的语法如下所示: 复制 { fn CONVERT (value-exp, data-type) } /* ODBC CAST (value-exp AS data-type) /* SQL92 SQL-92 CAST 函数要求哪些数据类型可以转换为其他数据类型。 (有关详细信息,请参阅 SQL-92 规范。) 在 ...
This is why you may need to cast an integer to a string in SQL. Achieve that with the following MySQL query: Copy 1 SELECT CAST(42 AS CHAR) The result will be the text representation of 42 : u201c42u201d is text Awesome! You are now a CAST SQL expert! SQL CAST Function: ...
SqlFunction表示SQL语句中的函数调用, 如SqlCastFunction表示cast函数, 在解析阶段所有自定义函数都会被表示为SqlUnresolvedFunction, 在验证阶段才会转化为对应的SqlUserDefinedFunction. SqlSelectOperator表示整个SELECT查询语句. SqlBinaryOperator表示二元运算, 如WHERE子句中的=运算. ...
