How to search a value in entire database

Question: How to search a value in entire database

Answer:
We created on Stored Procedure SearchAllTables
The output of this stored procedure contains two columns:

- 1) The table name and column name in which the search string was found
- 2) The actual content/value of the column (Only the first 3630 characters are displayed)


Create this procedure in the required database and here is how you run it:


Here is the complete stored procedure code:

CREATE PROC SearchAllTables
(
               @SearchStr nvarchar(100)
)
AS
BEGIN
               
               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')
                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
END
