Execute SQL Server scripts

Author: bazzargh (talk, contrib)

Description

With SQL Server 2000...a little bit untidy at present. This executes the script and dumps the output in the detail window. Todo: only dump the output if there's errors (and thats why I use '-b')

The Script

        ; path to the sql command line tools
  	ReadRegStr $R1 HKLM "SOFTWARE\Microsoft\Microsoft SQL Server\80\Tools\ClientSetup"
                            "SQLPath"
        ; the computer name. obviously you can prompt for a host
  	ReadRegStr $R2 HKLM "SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName"
                            "ComputerName"
	GetTempFileName $R0
	ExecWait '"$R1\Binn\isql.exe" -U "some-username" -P "some-password" -S  "$R2" -d master 
                  -i "some-file.sql" -o "$R0" -b'
 
	ClearErrors
        ; this dumps the logfile to the detail window
	FileOpen $R1 $R0 "r"
  	IfErrors FileOpenFailed
	MoreMessages:
		ClearErrors
		FileRead $R1 $R0
		IfErrors NoMoreMessages
		StrCpy $R0 $R0 -2 ; remove newline
		DetailPrint $R0
		Goto MoreMessages
	FileOpenFailed:
	DetailPrint "Can't read from $R0"
	NoMoreMessages:
	FileClose $R1
	ClearErrors

SQL Server 2005 and later

SQL Server 2005 replaced isql and osql with sqlcmd. I discuss a solution for these versions of SQL Server on this stackoverflow answer.
