Enum mz_sqllogictest::ast::Mode

pub enum Mode {
    Standard,
    Cockroach,
}

Specifies the dialect of a sqllogictest file. Different sqllogictest runners have slightly different behavior.

Variants

Standard

In Standard mode, expected query output is formatted so that every value is always on its own line, like so:

query II SELECT * FROM VALUES (1, 2), (3, 4)

1 2 3 4

Row boundaries are not visually represented, but they can be inferred because the number of columns per row is specified by the query directive.

Cockroach

In Cockroach mode, expected query output is formatted so that rows can contain multiple whitespace-separated columns:

query II SELECT * FROM VALUES (1, 2), (3, 4)

1 2 3 4

This formatting, while easier to parse visually, is thoroughly frustrating when column values contain whitespace, e.g., strings like “one two”, as there is no way to know where the column boundaries are. We jump through some hoops to make this work. You might want to refer to this upstream Cockroach commit 0 for additional details.
