求一正则表达式解析sql语句
如何用正则表达式，把上面的sql语句拆分成
1，insert
string tableName = contract
string fileds = ContractName,ContractRole,CtUpdate
string values="echo2","admin",now()

2, update
string tableName = contract
string fileds = ContractName,ContractRole,CtUpdate,update
string where = `Id`=2;

3, delete
 string tableName = contract
string where = `Id`=2;
