Seaching a value in a Table

The below stored procedure is used for searching a particular string in a table, if the string exists it will return the column name and correct search value.

Stored Procedure :

create PROC SearchTable
(@SearchStr nvarchar(100),
@TableName nvarchar(256))
AS
BEGIN
CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))
SET NOCOUNT ON
DECLARE @ColumnName nvarchar(128), @SearchStr2 nvarchar(110)
SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')
SET @ColumnName = ''
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')
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
SELECT ColumnName, ColumnValue FROM #Results
END

Output

Suppose we have a table called dbo.airways and the data it contains



here I would like to search the string 'amm', so my execute statement is like

EXEC SearchTable 'amm','dbo.airways'

Result :

Display all the table names from all the databases if they contains specific column name

The following query will display all the table names from all the databases if they contains specific column name. Here my column name is 'Y', so I want retrived all the table names from all the databases which are having 'Y' as one of the column. I am taking column name 'Y' in to one variable @Column_Val, so it will give all the database names and their corresponding table names which consists 'Y' as a column.


DECLARE @CMD VARCHAR(1000)

DECLARE @Column_Val VARCHAR(1000)

set @Column_Val='Y'

create table #TableNames ( DatabaseName sysname, TableName sysname)

SET @CMD = 'USE [?]; SELECT DB_NAME()DATABASE_NAME,A.name as Tablename from
( (select * from SYS.Tables) A join (SELECT * FROM SYS.columns where name like''' +@Column_Val+ ''') B on A.object_id=B.object_id)'

insert into #TableNames EXEC SP_MSFOREACHDB @CMD
SELECT * FROM #TableNames Where DatabaseName not in ( 'master','msdb', 'tempdb', 'model' )
drop table #TableNames
