sql-server - 如何在数据库中搜索文本字符串？

Question

有没有办法在整个 SQL Server 数据库中搜索文本字符串？

整个数据库是指表、视图、存储过程等。

Answer 1

如果您所说的数据库真的是指包括过程源代码在内的所有内容，那么最简单的方法可能是生成数据库转储并在结果文件中搜索字符串。这将比在信息模式上运行各种查询更简单。

Answer 2

这是在存储过程中搜索某些文本的代码

SELECT Distinct SO.Name
FROM sysobjects SO (NOLOCK)
INNER JOIN syscomments SC (NOLOCK) on SO.Id = SC.ID
AND SO.Type = 'P'
AND SC.Text LIKE '%test%'
ORDER BY SO.Name

Answer 3

我得到了使用存储过程显示/搜索所有表、列和 SP 的解决方案：

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

-- Copyright © 2013 Peter Nold. All rights reserved.
-- Purpose: To search all columns of all tables for a given search string

CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))

SET NOCOUNT ON

DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110), @myCount varchar(255)
SET  @TableName = ''
SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')

/* debug */
print '************************************************************'
print 'Starting Search For: ' + @SearchStr2
print '************************************************************'

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 QUOTENAME(COLUMN_NAME) > @ColumnName
        )

        IF @ColumnName IS NOT NULL
        BEGIN

            -- debug
            print 'Searching the field: ' + @TableName + '.' + @ColumnName

            INSERT INTO #Results
            EXEC
            (
                'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(CONVERT(varchar(max), ' + @ColumnName + '), 3630) 
                FROM ' + @TableName + ' (NOLOCK) ' +
                ' WHERE CONVERT(varchar(max), ' + @ColumnName + ') LIKE ' + @SearchStr2
            )
        END
    END 
END

SELECT ColumnName, ColumnValue FROM #Results

SET @myCount = 'Found in #columns: ' + cast((select count(*) from #Results) AS VARCHAR)
print '************************************************************'
print @myCount
print '************************************************************'

END
