Fin Table By Value

Question

Hello,

I have an Network Performance Monitoring tools, and i create custom script to get some values for windows server. The script is run successful and return a value let say 565523.

The problem is i want to make custom report and the vendor is not provide support for reporting using custom query. The database contains lot of table, and i want to know can we find table by searching the value only? Example query all tables where contain record 565523.

Looking for a needle in a haystack?

Try this, but beware that this can take a long time in a big database with many tables and columns. You need to adjust the selection of types depending on what sort of value you are looking for.

SELECT 'IF EXISTS (SELECT *
                   FROM   ' + quotename(s.name) + '.' + quotename(t.name) + '
                   WHERE  ' + quotename(c.name) + ' = 11000)
           SELECT  ' + quotename(s.name, '''') + ' AS "schema", 
                   ' + quotename(t.name, '''') + ' AS "table", 
                   ' + quotename(c.name, '''') + ' AS "column"'
FROM   sys.schemas s
JOIN   sys.tables t ON s.schema_id = t.schema_id
JOIN   sys.columns c ON t.object_id = c.object_id
WHERE  type_name(c.system_type_id) IN ('int', 'bigint')

Hi @Handian Sudianto

See the answer from this similar thread: Search all tables, all columns for a specific value SQL Server

DECLARE @SearchStr nvarchar(100)
SET @SearchStr = '565523'

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 = 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
