我一直在使用此SQL脚本搜索数据库中每个表的每个字段以获取特定值。SQL搜索全部表
但它似乎不适用于数字字段。 （所以，如果我把121放入搜索，并有一个字段是十进制字段与121.000或121等，它不提供结果）
这是超出我的SQL技能来修改此脚本，所以我希望这里有人可以帮忙。
这不适用于生产用途。但它偶尔也是一个有用的工具。
DECLARE @Tablenames VARCHAR(500)
DECLARE @SearchStr NVARCHAR(60)
DECLARE @GenerateSQLOnly Bit
SELECT @Tablenames =''
SELECT @SearchStr ='16'
SELECT @GenerateSQLOnly = 0
/*
Variables and usage
@Tablenames -- Provide a single table name or multiple table name with comma seperated.
If left blank , it will check for all the tables in the database
@SearchStr -- Provide the search string. Use the '%' to coin the search.
EX : X%--- will give data staring with X
%X--- will give data ending with X
%X%--- will give data containig X
@GenerateSQLOnly -- Provide 1 if you only want to generate the SQL statements without seraching the database.
By default it is 0 and it will search.
Samples :
1. To search data in a table
@Tablenames = 'T1'
,@SearchStr = '%TEST%'
The above sample searches in table T1 with string containing TEST.
2. To search in a multiple table
@Tablenames = 'T2'
,@SearchStr = '%TEST%'
The above sample searches in tables T1 & T2 with string containing TEST.
3. To search in a all table
@Tablenames = '%'
,@SearchStr = '%TEST%'
The above sample searches in all table with string containing TEST.
4. Generate the SQL for the Select statements
@Tablenames = 'T1'
,@SearchStr = '%TEST%'
,@GenerateSQLOnly = 1
