如何在SQL Server的数据库中搜索字符串 [英] How to search a string in databases of SQL Server

问题描述

此查询可以从任何SQL Server数据库的所有表/视图中搜索任何字符串值（表名，表数据等），当您将任何字符串放在此处的文本时将搜索该数据库中存在的所有表/视图的给定字符串

  DECLARE @SearchStr nvarchar（100）
 SET @SearchStr ='your text here'
 
 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不是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'）
和QUOTENAME（COLUMN_NAME）> @ColumnName 
）
 
如果@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 
  

$ b b

但我喜欢在过程/函数/触发器中搜索给定字符串，以及SQL Server 2005中是否存在任何查询。因为此查询不在这些区域中搜索。

解决方案

/ triggers

这实际上要容易得多。

 code> SELECT OBJECT_NAME（object_id），定义
 FROM sys.sql_modules 
 WHERE定义LIKE'％'+ @ SearchStr +'％'
  
  SELECT ColumnName，ColumnValue 
 FROM @Results 
 UNION ALL 
 SELECT OBJECT_NAME（object_id），definition 
 FROM sys.sql_modules 
 WHERE定义LIKE'％'+ @ SearchStr +'％'
  
他们分开一个接一个作为单独的语句。
 
This Query can search any string value (table name, table data etc) from all the tables/views of any SQL Server database, when you will place any string at "your text here" it will search your given string from all the tables/views exist in that database,
DECLARE @SearchStr nvarchar(100) 
    SET @SearchStr = 'your text here'

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')
                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
But I like to search given string in the procedures/functions/triggers as well is there any query exist in SQL Server 2005. As this query does not search in these areas.
解决方案

  
search given string in the procedures/functions/triggers
This is actually far easier.
SELECT OBJECT_NAME(object_id), definition
  FROM sys.sql_modules
 WHERE definition LIKE '%'+@SearchStr+'%'
One way to use it is to add it to the end of your TSQL code, i.e modify the last SELECT:
SELECT ColumnName, ColumnValue
  FROM @Results
 UNION ALL
SELECT OBJECT_NAME(object_id), definition
  FROM sys.sql_modules
 WHERE definition LIKE '%'+@SearchStr+'%'
Personally, I'd just run them separately one after the other as separate statements.
