MS SQLSERVER中如何得到表的创建语句2009-11-19肖波MS SQLSERVER只能得到存储过程的创建语句,方法如下:sp_helptext procedureName但是往往我们需要得到表的创建语句,比如说在数据库升级的时候判断某个表是否已经改变,或者已经有一个表存在,但不知道它的创建语句是什么,字段有没有约束,有没有主键,创建了哪些索引等等.下面我给出一个存储过程,供读者参考.该存储过程可以得到你想得到的所有的表的创建语句,包括和表有关的索引的创建语句.SQLSERVER2000/2005 下的代码create procedure SP_GET_TABLE_INFO @ObjName varchar(128) /**//* The table to generate sql script */ as declare @Script varchar(255) declare @ColName varchar(30) declare @ColID TinyInt declare @UserType smallint declare @TypeName sysname declare @Length TinyInt declare @Prec TinyInt declare @Scale TinyInt declare @Status TinyInt declare @cDefault int declare @DefaultID TinyInt declare @Const_Key varchar(255) declare @IndID SmallInt declare @IndStatus Int declare @Index_Key varchar(255) declare @DBName varchar(30) declare @strPri_Key varchar (255) /**//* ** Check to see the the table exists and initialize @objid. */ if not Exists(Select name from sysobjects where name = @ObjName) begin select @DBName = db_name() raiserror(15009,-1,-1,@ObjName,@DBName) return (1) end create table #spscript ( id int IDENTITY not null, Script Varchar(255) NOT NULL, LastLine tinyint ) declare Cursor_Column INSENSITIVE CURSOR for Select a.name,a.ColID,a.usertype,b.name,a.length,a.prec,a.scale,a.Status, a.cDefault, case a.cdefault when 0 then " " else (select c.Text from syscomments c where a.cdefault = c.id) end const_key from syscolumns a, systypes b where object_name(a.id) = @ObjName and a.usertype = b.usertype order by a.ColID set nocount on Select @Script = "Create table " + @ObjName + "(" Insert into #spscript values(@Script,0) /**//* Get column information */ open Cursor_Column fetch next from Cursor_Column into @ColName,@ColID,@UserType,@TypeName,@Length,@Prec,@Scale, @Status,@cDefault,@Const_Key Select @Script = "" while (@@FETCH_STATUS <> -1) begin if (@@FETCH_STATUS <> -2) begin Select @Script = @ColName + " " + @TypeName if @UserType in (1,2,3,4) Select @Script = @Script + "(" + Convert(char(3),@Length) + ") " else if @UserType in (24) Select @Script = @Script + "(" + Convert(char(3),@Prec) + "," + Convert(char(3),@Scale) + ") " else Select @Script = @Script + " " if ( @Status & 0x80 ) > 0 Select @Script = @Script + " IDENTITY(1,1) " if ( @Status & 0x08 ) > 0 Select @Script = @Script + " NULL " else Select @Script = @Script + " NOT NULL " if @cDefault > 0 Select @Script = @Script + " DEFAULT " + @Const_Key end fetch next from Cursor_Column into @ColName,@ColID,@UserType,@TypeName,@Length,@Prec,@Scale, @Status,@cDefault,@Const_Key if @@FETCH_STATUS = 0 begin Select @Script = @Script + "," Insert into #spscript values(@Script,0) end else begin Insert into #spscript values(@Script,1) Insert into #spscript values(")",0) end end Close Cursor_Column Deallocate Cursor_Column /**//* Get index information */ Declare Cursor_Index INSENSITIVE CURSOR for Select name,IndID,status from sysindexes where object_name(id)=@ObjName and IndID > 0 and IndID<>255 order by IndID /**//*增加了对InDid为255的判断*/ Open Cursor_Index Fetch Next from Cursor_Index into @ColName, @IndID, @IndStatus while (@@FETCH_STATUS <> -1) begin if @@FETCH_STATUS <> -2 begin declare @i TinyInt declare @thiskey varchar(50) declare @IndDesc varchar(68) /**//* string to build up index desc in */ Select @i = 1 while (@i <= 16) begin select @thiskey = index_col(@ObjName, @IndID, @i) if @thiskey is null break if @i = 1 select @Index_Key = index_col(@ObjName, @IndID, @i) else select @Index_Key = @Index_Key + ", " + index_col(@ObjName, @IndID, @i) select @i = @i + 1 end if (@IndStatus & 0x02) > 0 Select @Script = "Create unique " else Select @Script = "Create " if @IndID = 1 select @Script = @Script + " clustered " if (@IndStatus & 0x800) > 0 select @strPri_Key = " PRIMARY KEY (" + @Index_Key + ")" else select @strPri_Key = "" if @IndID > 1 select @Script = @Script + " nonclustered " Select @Script = @Script + " index " + @ColName + " ON "+ @ObjName + "(" + @Index_Key + ")" Select @IndDesc = "" /**//* ** See if the index is ignore_dupkey (0x01). */ if @IndStatus & 0x01 = 0x01 Select @IndDesc = @IndDesc + " IGNORE_DUP_KEY" + "," /**//* ** See if the index is ignore_dup_row (0x04). */ /**//* if @IndStatus & 0x04 = 0x04 */ /**//* Select @IndDesc = @IndDesc + " IGNORE_DUP_ROW" + "," */ /**//* 2000 不在支持*/ /**//* ** See if the index is allow_dup_row (0x40). */ if @IndStatus & 0x40 = 0x40 Select @IndDesc = @IndDesc + " ALLOW_DUP_ROW" + "," if @IndDesc <> "" begin Select @IndDesc = SubString( @IndDesc, 1, DataLength(@IndDesc) - 1 ) Select @Script = @Script + " WITH " + @IndDesc end /**//* ** Add the location of the data. */ end if (@strPri_Key = "") Insert into #spscript values(@Script,0) else update #spscript set Script = Script + @strPri_Key where LastLine = 1 Fetch Next from Cursor_Index into @ColName, @IndID, @IndStatus end Close Cursor_Index Deallocate Cursor_Index Select Script from #spscript set nocount off return (0)
