示例1: ParseType
protected virtual String ParseType(FieldType type) {
List<String> parsed = new List<String>();
Length length = type.FirstOrDefault(attribute => attribute is Length) as Length;
if (type is StringType) {
parsed.Add(String.Format("VARCHAR({0})", length == null ? 255 : length.Value));
}
else if (type is IntegerType) {
parsed.Add("INTEGER");
}
else if (type is DateTimeType) {
parsed.Add("DATETIME");
}
// Enforce NOT NULL and inline primary key when AutoIncrement is used.
if (type.Any(attribute => attribute is AutoIncrement) == true) {
parsed.Add("PRIMARY KEY AUTOINCREMENT NOT NULL");
}
else if (type.Any(attribute => attribute is Nullable) == false) {
parsed.Add("NOT NULL");
}
return String.Join(" ", parsed);
}
示例2: ParseType
protected virtual String ParseType(FieldType type) {

Unsigned unsigned = type.FirstOrDefault(attribute => attribute is Unsigned) as Unsigned;
if (type is StringType) {
parsed.Add(String.Format("VARCHAR({0})", length == null ? 255 : length.Value));
}
else if (type is IntegerType) {
parsed.Add("INT");
if (unsigned != null) {
parsed.Add("UNSIGNED");
}
}
else if (type is DateTimeType) {
