答案简短:否
中等回答: MAYBE
答案很长:这取决于您的TSQL中的内容以及您希望投入多少时间和精力。
TSQL不是MySQL方言的子集。所以存在一些没有MySQL转换的TSQL。但是,两种语言之间的重叠非常重要,在某种程度上,转换只是语法问题。
这不是一个新问题,有些人试图解决它。快速谷歌搜索“tsql to mysql”产生一些有希望的结果,特别是这个项目,它试图将存储过程从TSQL转换为MySQL:
http://sourceforge.net/projects/tsql2mysql/
这可能不会完全解决你的问题,但它至少是一个开始。

我刚刚获得了一个tsql脚本。
我的解决方案是:
我对我的代码并不感到骄傲,但它对我有用。
4个文件位于同一个文件夹中:
批量调用sqlcmd
@echo off
set host= (local)
set schema=database
set user=user
set pass=pass
cd %cd%
rem tables
SQLCMD -S %host% -d %schema% -U %user% -P %pass% -s "" -h-1 -W -i "%CD%\mysql_export_table.sql" -o "%CD%\%schema%_tables.sql"
rem data
SQLCMD -S %host% -d %schema% -U %user% -P %pass% -s "" -h-1 -W -i "%CD%\mysql_export_data.sql" -o "%CD%\%schema%_data.sql"
rem fk
SQLCMD -S %host% -d %schema% -U %user% -P %pass% -s "" -h-1 -W -i "%CD%\mysql_export_fk.sql" -o "%CD%\%schema%_fk.sql"
然后tsql脚本导出表模式mysql_export_table.sql
SET NOCOUNT ON;
SET QUOTED_IDENTIFIER ON;
DECLARE @table_name as varchar(max)
DECLARE view_cursor CURSOR FOR
SELECT Table_name FROM information_schema.tables where TABLE_TYPE = 'BASE TABLE' and table_name not like 'sys%'
OPEN view_cursor
FETCH NEXT FROM view_cursor
INTO @table_name
WHILE @@FETCH_STATUS = 0
BEGIN
select ''
select '/*** TABLE '+@table_name+' ***/ '
select 'DROP TABLE IF EXISTS ' + QUOTENAME(@table_name, '`') + ';'
select ''
select 'CREATE TABLE ' + QUOTENAME(@table_name, '`') + ' ('
-- column declaration
select
CHAR(9)
+ QUOTENAME(Column_Name, '`') + ' ' +
DATA_TYPE
+
coalesce( '(' + cast(coalesce(replace(CHARACTER_MAXIMUM_LENGTH, -1, 2500), null) as varchar) + ')', '')
+ ' ' +
case IS_NULLABLE WHEN 'NO' then 'NOT ' else '' end + 'NULL'
+ ' ' +
case when COLUMNPROPERTY(object_id(TABLE_NAME), COLUMN_NAME, 'IsIdentity') = 1 then 'AUTO_INCREMENT' else '' end
--coalesce( 'DEFAULT ' + replace(replace(replace(COLUMN_DEFAULT, '(', ''), ')', ''), 'getdate', null), '')
+','
FROM information_schema.COLUMNS where TABLE_NAME = @table_name
-- PK
select coalesce('PRIMARY KEY (' +STUFF((
SELECT distinct ', ' + QUOTENAME(Col.Column_Name,'`') from
INFORMATION_SCHEMA.TABLE_CONSTRAINTS Tab inner join
INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE Col on Col.Constraint_Name = Tab.Constraint_Name AND Col.Table_Name = Tab.Table_Name
WHERE
Constraint_Type = 'PRIMARY KEY '
AND Col.Table_Name = @table_name
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') , 1, 1, '')+ ')', '')
select ') Engine InnoDB;'
FETCH NEXT FROM view_cursor
INTO @table_name
END
CLOSE view_cursor;
DEALLOCATE view_cursor;
然后是数据mysql_export_data.sql的脚本
SET NOCOUNT ON;
SET QUOTED_IDENTIFIER ON;
DECLARE @table_name as varchar(max)
declare @column_names as varchar(max)
DECLARE view_cursor CURSOR FOR
SELECT Table_name FROM information_schema.tables where TABLE_TYPE = 'BASE TABLE' and table_name not like 'sys%'
OPEN view_cursor
FETCH NEXT FROM view_cursor
INTO @table_name
WHILE @@FETCH_STATUS = 0
BEGIN
select ''
select '/*** TABLE '+@table_name+' ***/ '
select @column_names = STUFF(( SELECT ', ' + QUOTENAME(Column_Name, '`') from INFORMATION_SCHEMA.COLUMNS WHERE Table_Name = @table_name ORDER BY ORDINAL_POSITION FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') , 1, 1, '')
select 'REPLACE INTO '+ QUOTENAME(@table_name, '`') +'('+ @column_names+ ') VALUES '
select @column_names = 'SELECT DISTINCT ''('+ STUFF(( SELECT ', '','''''' + coalesce(replace(cast(' + QUOTENAME(Column_Name) +' as varchar(200)), '''''''',''''), '''') + ''''''''' from INFORMATION_SCHEMA.COLUMNS WHERE Table_Name = @table_name ORDER BY ORDINAL_POSITION FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') , 1, 4, '') + '+''),'' FROM ' + QUOTENAME(@table_name)
exec (@column_names)
FETCH NEXT FROM view_cursor
INTO @table_name
END
CLOSE view_cursor;
DEALLOCATE view_cursor;
最后FK脚本
SET NOCOUNT ON;
SET QUOTED_IDENTIFIER ON;
-- FK
-- foreign keys
SELECT
'ALTER TABLE',
' '+ QUOTENAME(OBJECT_NAME(fkcol.[object_id]), '`'),
--ADD CONSTRAINT `recherche_ibfk_1` FOREIGN KEY (`notaire_compte_id`) REFERENCES `notaire_compte` (`id`) ON DELETE CASCADE ON UPDATE CASCADE;
' ADD CONSTRAINT',
' ' + QUOTENAME(fk.name, '`'),
' FOREIGN KEY',
' (' + QUOTENAME(fkcol.name, '`') +')',
' REFERENCES',
' ' + QUOTENAME(OBJECT_NAME(pkcol.[object_id]), '`'),
' (' + QUOTENAME(pkcol.name, '`') + ');',
CHAR(13)
FROM sys.foreign_keys AS fk
INNER JOIN sys.foreign_key_columns AS fkc
ON fk.[object_id] = fkc.constraint_object_id
INNER JOIN sys.columns AS fkcol
ON fkc.parent_object_id = fkcol.[object_id]
AND fkc.parent_column_id = fkcol.column_id
INNER JOIN sys.columns AS pkcol
ON fkc.referenced_object_id = pkcol.[object_id]
AND fkc.referenced_column_id = pkcol.column_id
ORDER BY fkc.constraint_column_id;
我知道,我知道......它非常难看......
此脚本的目标不是将TSQL转换为Mysql,而是将数据库从MSSQL导出到Mysql
在表格结果上你必须执行正则表达式替换(记事本++) 替换",\ r \ n \ r \ n)" by" \ r \ n \ r \ n)"
在数据结果上替换",\ r \ n \ r \ n / " by"; \ r \ n \ r \ n / "
执行顺序:表格 - >数据 - > FK

其他人是否说,这取决于你的特定字符串的长度。
但是,我建议您不要将Transact-SQL转换为MySQL。
如果您考虑一下,我认为您会发现要将其转换为ODBC。
然后明年,公司希望您将其转移到Oracle或Access ...
