是不是TSQLConnection的设置的问题？？

object Cfb: TSQLConnection
ConnectionName = 'IBConnection'
DriverName = 'Interbase'
GetDriverFunc = 'getSQLDriverINTERBASE'
LibraryName = 'dbexpint.dll' ————————这个有没有问题？
LoadParamsOnConnect = True
LoginPrompt = False
Params.Strings = (
'DriverName=Interbase'
'Database=1x.xxx.xxx.xxx:d:\firebird\db\sett.gdb'
'RoleName=RoleName'
'User_Name=sysdba'
'Password=masterkey'
'ServerCharSet='
'SQLDialect=1'
'ErrorResourceFile='
'LocaleCode=0000'
'BlobSize=-1'
'CommitRetain=False'
'WaitOnLocks=True'
'Interbase TransIsolation=ReadCommited'
'Trim Char=False')
