Question

sm_Value是TEXT列，我需要将其转换为INT。

事实上只有两个人会弄乱这个表，这个列将是数字的（幽默我）

我收到此错误消息：

Msg 206，Level 16，State 2，Procedure User_Password_Date_Interval_Check，Line 10
操作数类型冲突：文本与int
不兼容

我试过了：

SELECT CONVERT(INT, sm_Value)) 
FROM Setting_Misc

但我仍然得到错误。

IF EXISTS (SELECT * FROM sysobjects 
           WHERE type = 'P' AND name = 'User_Password_Date_Interval_Check')
BEGIN
    PRINT 'Dropping Procedure User_Password_Date_Interval_Check'
    DROP  Procedure  User_Password_Date_Interval_Check
END
GO

PRINT 'Creating Procedure User_Password_Date_Interval_Check'
GO

CREATE Procedure User_Password_Date_Interval_Check
    @ua_pk uniqueidentifier
AS
    DECLARE @PasswordExpireDays INT

    SELECT 
        CONVERT(INT, CONVERT(VARCHAR(MAX), sm_Value)) 
    FROM Setting_Misc

    SELECT
        @PasswordExpireDays = COALESCE(sm_Value,0)
    FROM
        Setting_Misc AS sm
    INNER JOIN
        Syndicates As syn ON sm.syn_fk = syn.syn_pk
    INNER JOIN
        Company As c ON c.syn_fk = syn.syn_pk
    INNER JOIN
        User_Accounts As ua ON ua.c_fk = c.c_pk
    WHERE 
        sm.sm_Setting = 'PasswordExpireDays'
GO

GRANT EXEC ON User_Password_Date_Interval_Check TO WEB

您必须在设置变量的位置进行转换。

IF EXISTS (SELECT * FROM sysobjects 
           WHERE type = 'P' AND name = 'User_Password_Date_Interval_Check')
BEGIN
    PRINT 'Dropping Procedure User_Password_Date_Interval_Check'
    DROP  Procedure  User_Password_Date_Interval_Check
END
GO

PRINT 'Creating Procedure User_Password_Date_Interval_Check'
GO

CREATE Procedure User_Password_Date_Interval_Check
    @ua_pk uniqueidentifier
AS
    DECLARE @PasswordExpireDays INT
    --This conversion doesn't cascade down to the next SELECT statement
    SELECT 
        CONVERT(INT, CONVERT(VARCHAR(MAX), sm_Value)) 
    FROM Setting_Misc

    SELECT
        --Here is what has to change
        --@PasswordExpireDays = COALESCE(sm_Value,0)
          @PasswordExpireDays = CONVERT(INT, CONVERT(VARCHAR(MAX), sm_Value)) 
    FROM
        Setting_Misc AS sm
    INNER JOIN
        Syndicates As syn ON sm.syn_fk = syn.syn_pk
    INNER JOIN
        Company As c ON c.syn_fk = syn.syn_pk
    INNER JOIN
        User_Accounts As ua ON ua.c_fk = c.c_pk
    WHERE 
        sm.sm_Setting = 'PasswordExpireDays'
GO

GRANT EXEC ON User_Password_Date_Interval_Check TO WEB
