Sorry I haven't replied sooner. I am not sure what response you want. I don't know the table structure of your schema, or the format of the data file, so I can't suggest a more specific solution.

One thing is certain: you do need to supply syntactically correct SQL statements at all times. SQL does not recognize the syntax of leaving a field empty in a list of values. That is, you must supply a value, or else NULL. Also, the number of values in the row constructor must be equal to the number of columns specified for the INSERT.

There's also a method to import a bulk amount of data using the LOAD DATA statement, but this also requires that there be a value on each row for every column, or else "\N" to signify NULL. A zero-length string value is interpreted as ''. For example you could load a datafile containing something like this:


Importing the line above would put the string '' into the third column of your table. This is not the same as NULL.

See for more information on LOAD DATA.
