Question

我正在尝试使用搜索字符串搜索整个数据库。为此，我需要检查表，视图，存储过程+所有表中的所有数据。

我能够搜索所有数据库对象，但是当我需要搜索表时有一点问题，我需要搜索单元格，如果搜索字符串存在于该特定单元格中，我需要显示表名，找到搜索字符串的单元格的特定行和列名称上的所有列。

我正在使用Sorna Kumar Maduraj 的代码来获取整行，我被卡住了以显示搜索字符串所在位置的列

例如

名为Searchtable的表在i中搜索的搜索字符串（假设它是AdminCd）位于2个不同列的特定行中（假设列名为ColumnA，ColumnB）

我的输出是表名 - 行数据 - 列名（ColumnA，ColumnB）

我唯一的问题是假设在同一个表中，一行包含2列中的字符串，而不同的行包含4列中的搜索字符串，我需要以不同的方式显示列作为输出

我使用的代码，生病了下面

DECLARE  @Tablenames VARCHAR(500)
DECLARE @SearchStr NVARCHAR(60)
DECLARE @GenerateSQLOnly Bit = 0
SET @Tablenames = 'TableName'
SET @SearchStr = '%AdminCd%'
    SET NOCOUNT ON
    DECLARE @MatchFound BIT -- To check wether any match is found or not 
   SELECT @MatchFound = 0
    DECLARE @CheckTableNames Table -- To check the tables that need to be searched 
(
Tablename sysname
)
DECLARE @SQLTbl TABLE -- For Table Name

 Tablename      SYSNAME
,WHEREClause    VARCHAR(MAX)
,SQLStatement   VARCHAR(MAX)
