执行完下面的函数之后，再就不能对这个数据库进行update了（select查询可以）。请各位帮我看看问题出在哪里了？谢谢
void Function()
{
sqlite3 *db;
char *zErrMsg = 0;
int rc=0;
rc = sqlite3_open( CStringToChar(dbFilePath) ,&db);
rc = sqlite3_exec(db, "PRAGMA synchronous = OFF; ", 0,0,0);
if (rc)
{
CString str,str1;
str1 = _T("can't open database:");
CString str2( sqlite3_errmsg(db) );
str = str1+str2;
MessageBox(NULL,str,_T("warnning"),NULL);
return;
}
rc = sqlite3_exec(db,"begin;",0,0,0);
char *sqlStatement;
CString stateCString = _T("SELECT x,y from ") + toGetTableName + _T(";");
sqlStatement =CStringToChar(stateCString);
sqlite3_stmt *stmt = NULL;
int result = sqlite3_prepare_v2(db, sqlStatement,-1,&stmt,NULL);
if (result == SQLITE_OK)
{
while ( sqlite3_step(stmt)== SQLITE_ROW)
{
double x,y;
x = atof( (const char *) sqlite3_column_text(stmt,0));
y = atof( (const char *) sqlite3_column_text(stmt,1));
int Idnum;
Idnum =atoi( (const char *)sqlite3_column_text(stmt,2));
}
}
sqlite3_finalize(stmt);
sqlite3_exec(db,"commit;",0,0,0);
sqlite3_close(db);
}
