StructFromCreateTable

Given some SQL, it finds the CREATE TABLE instruction for the given tableName. (this is so it can find one entry from a file with several SQL commands. But it may break on a complex file, so try to only feed it simple sql files.)

From that, it pulls out the members to create a simple struct based on it.

It's not terribly smart, so it will probably break on complex tables.

Data types handled:

INTEGER, SMALLINT, MEDIUMINT -> D's int
TINYINT -> D's bool
BIGINT -> D's long
TEXT, VARCHAR -> D's string
FLOAT, DOUBLE -> D's double

It also reads DEFAULT values to pass to D, except for NULL. It ignores any length restrictions.

string sql
string tableName

Bugs

  • Skips all constraints
  • Doesn't handle nullable fields, except with strings
  • It only handles SQL keywords if they are all caps

This, when combined with SimpleDataObject!(), can automatically create usable D classes from SQL input.
