Quickly Search For Data All Over Database

Many a time we come across a scenario where we want to fetch data from all over database tables based on delimited some string. It is very difficult and time to consume to write different queries based on every table/column to quickly search for data all over the SQL Database. But I would prefer passing the delimited string to the stored procedure and fetching data with table and column names.


DECLARE @SearchStr nvarchar(max)
SET @SearchStr = '45206'
 
CREATE TABLE #Results (ColumnName nvarchar(max), ColumnValue nvarchar(max))
SET NOCOUNT ON
 
DECLARE @TableName nvarchar(max), @ColumnName nvarchar(max), @SearchStr2 nvarchar(max)
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

DECLARE @SearchStr nvarchar(max)

SET @SearchStr = '45206'

CREATE TABLE #Results (ColumnName nvarchar(max), ColumnValue nvarchar(max))

SET NOCOUNT ON

DECLARE @TableName nvarchar(max), @ColumnName nvarchar(max), @SearchStr2 nvarchar(max)

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)

) = 0

)

WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL)

BEGIN

SET @ColumnName =

(

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

SELECT ColumnName, ColumnValue FROM #Results

DROP TABLE #Results
