在所有數據庫表中搜索PK或FK

Question

我試圖在我的SQL表中找到特定鍵的所有實例。該值是數字。

錯誤轉換數據類型的數字爲varchar

腳本

DECLARE @SearchStr varchar(100) 
SET @SearchStr = '6836755' 

CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630)) 

SET NOCOUNT ON 

DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110) 
SET @TableName = '' 
SET @SearchStr2 = @SearchStr--QUOTENAME('%' + @SearchStr + '%','''') 

WHILE @TableName IS NOT NULL 
BEGIN 
    SET @ColumnName = '' 
    SET @TableName = 
    (
     SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)) 
     FROM INFORMATION_SCHEMA.TABLES 
     WHERE TABLE_TYPE = 'BASE TABLE' 
      AND QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @TableName 
      AND OBJECTPROPERTY(
        OBJECT_ID(
         QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) 
         ), 'IsMSShipped' 
          ) = 0 
    ) 

    WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL) 
    BEGIN 
     SET @ColumnName = 
     (
      SELECT MIN(QUOTENAME(COLUMN_NAME)) 
      FROM INFORMATION_SCHEMA.COLUMNS 
      WHERE TABLE_SCHEMA = PARSENAME(@TableName, 2) 
       AND TABLE_NAME = PARSENAME(@TableName, 1) 
       AND DATA_TYPE IN ('char', 'varchar', 'nchar', 'nvarchar', 'int', 'decimal') 
       AND QUOTENAME(COLUMN_NAME) > @ColumnName) 

     IF @ColumnName IS NOT NULL 
     BEGIN 
      INSERT INTO #Results 
      EXEC 
      (
       'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630) FROM ' + @TableName + ' (NOLOCK) ' + 
       ' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2 
      ) 
     END 
    END 
END 

SELECT ColumnName, ColumnValue FROM #Results 

DROP TABLE #Results 

這個偉大的工程爲文本值：

我使用的腳本以下時收到此錯誤。我要麼需要一種方法來修改它，以便搜索數字，或者如果它更容易，可以識別給定FK所在的每個表。

玩弄：SQL Server: Get table primary key using sql query

：

SELECT KU.table_name as TABLENAME,column_name as PRIMARYKEYCOLUMN, * 
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS AS TC 
INNER JOIN 
    INFORMATION_SCHEMA.KEY_COLUMN_USAGE AS KU 
      ON TC.CONSTRAINT_TYPE = 'PRIMARY KEY' AND 
      TC.CONSTRAINT_NAME = KU.CONSTRAINT_NAME 
ORDER BY KU.TABLE_NAME, KU.ORDINAL_POSITION; 

略有修改
