Question

我有以下T SQL语句，但始终收到错误

关键字“ CONVERT”附近的语法错误

我要去哪里错了？

DECLARE @NSQL2 NVARCHAR(MAX)
DECLARE @SOURCETABLE NVARCHAR(MAX)

SELECT TOP 1 @SOURCETABLE = TABLE_NAME 
FROM INFORMATION_SCHEMA.TABLES 
WHERE TABLE_NAME LIKE 'IN_PRODUCT________________%' 
  AND TABLE_TYPE = 'BASE TABLE'

SET @NSQL2 = 'UPDATE [' + @SOURCETABLE + '] SET OnSale = '''+ CONVERT(nvarchar(MAX),OnSale, 112)+'''

EXEC SP_EXECUTESQL @NSQL2

Answer 1

尝试一下：

    SET @NSQL2 = 'UPDATE ' + QUOTENAME(@SOURCETABLE) 
                 + ' SET OnSale = CONVERT(nvarchar(10),OnSale, 112)'

Answer 2

我通过以下方法使它起作用：

SET @NSQL = 'UPDATE [' + @SOURCETABLE + '] SET OnSale =  CONVERT(nvarchar,CAST(OnSale AS DATETIME), 120)'

Answer 3

您是否打算将Convert语句作为文字包含在字符串中？

SET @NSQL2 = 'UPDATE [' + @SOURCETABLE + '] SET OnSale = CONVERT(nvarchar(MAX),OnSale, 112)'

错误“关键字'CONVERT'附近的语法不正确”
