有没有办法在 SQL Server 的数据库的所有表中搜索字符串?
我想搜索字符串 say john。结果应显示包含john.
john
如果你和我一样,在生产环境中有一定的限制,你可能希望使用表变量而不是临时表,使用临时查询而不是创建过程。
当然根据你的 sql server 实例,它必须支持表变量。
我还添加了一条 USE 语句来缩小搜索范围
USE DATABASE_NAME DECLARE @SearchStr nvarchar(100) = 'SEARCH_TEXT' DECLARE @Results TABLE (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
