For this answer, where do I input the string I want to search for? In this case, 'john-wick'

The goal is to search which table and which column stored the data called 'john-wick'

Am using DBeaver to access the SQL Server database

CREATE PROC [dbo].[SearchAllTablesByRecord]
(
    @SearchStr NVARCHAR(100)

    DECLARE @ColumnList NVARCHAR(2048), @ColumnJoin NVARCHAR(2048)
    SET  @TableName = ''
    SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')

    WHILE @TableName IS NOT NULL
    BEGIN
            SET @TableName = 
            (
                    SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))

                   WHERE           TABLE_TYPE = 'BASE TABLE'

            )
            SET @ColumnJoin = REPLACE(@ColumnList,',','+')
