Overview ¶

Package exprtest holds the render-only fixtures that the tests of a feature package (arrayop, fts, ...) need to see the SQL and arguments of a predicate or expression: a one-column projection row and a DB over the recording fake driver. Nothing here runs a statement.

Functions ¶

func Compile ¶

func Compile(name dialect.Name, p momo.Predicate) (momo.Compiled, error)

Compile renders the predicate in "SELECT COUNT(*) FROM docs WHERE p" for the dialect and returns the statement.

func CompileColumns ¶

func CompileColumns(name dialect.Name, cols ...momo.Expr) (momo.Compiled, error)

CompileColumns renders "SELECT cols FROM documents" for the dialect and returns the statement, for tests of a value expression.

func DB ¶

func DB(name dialect.Name) *momo.DB

DB opens a DB for the dialect over a driver that records statements and runs none.

Types ¶

type Pair ¶

type Pair struct {
	K int64
	N int64
}

Pair is a two-column projection fixture with no table of its own, for rendering a select list of an expression and a count, for example a grouped extraction. Select it with Columns(expr, momo.CountAll()).

func (*Pair) MomoMeta ¶

func (*Pair) MomoMeta() *momo.Meta[Pair]

MomoMeta makes Pair a model for momo.Select.

type Tally ¶

type Tally struct{ N int64 }

Tally is a projection fixture with a single count column and no table of its own. Select it with Columns(momo.CountAll()).

func (*Tally) MomoMeta ¶

func (*Tally) MomoMeta() *momo.Meta[Tally]

MomoMeta makes Tally a model for momo.Select.

type TextTally ¶

type TextTally struct {
	S string
	N int64
}

TextTally is a projection fixture with a text column and a count column, for statements that select a computed bucket next to COUNT(*).

func (*TextTally) MomoMeta ¶

func (*TextTally) MomoMeta() *momo.Meta[TextTally]

MomoMeta makes TextTally a model for momo.Select.
