QSqlQuery does not execute

[weixj2003ld]

You could look at mQuery.executedQuery() to see if the the query executed by QSqlQuery really matches the one you enter in the command window.

I print the 'executedQuery()',and find that it execute ""LOAD DATA INFILE '"+fileName+"' INTO TABLE table1 FIELDS TERMINATED BY ' ' LINES TERMINATED BY '\r\n'"))" ,that is, it exectue the query as I type.

It could also be a transaction problem, maybe there is a COMMIT missing in your Qt code?

I have no transaction ,so there is no COMMIT.

By the way, if I exectue 'Insert' or 'update',it is ok.
