slonik-sql-tag-raw
Slonik SQL tag for constructing dynamic queries.
Warning
There are no known use cases for generating queries using raw
that aren't covered by nesting bound sql
expressions or by one of the other existing query building methods. raw
exists only as a mechanism to execute externally stored static queries (e.g. queries stored in files).
Usage
import {
raw,
} from 'slonik-sql-tag-raw';
raw
(
sql: string,
values?: $ReadOnlyArray<PrimitiveValueExpressionType>
) => RawSqlTokenType;
Raw/ dynamic SQL can be inlined using raw
, e.g.
sql`
SELECT 1
FROM ${raw('"bar"')}
`;
Produces:
{
sql: 'SELECT 1 FROM "bar"',
values: []
}
The second parameter of the raw
can be used to bind positional parameter values, e.g.
sql`
SELECT ${raw('$1', [1])}
`;
Produces:
{
sql: 'SELECT $1',
values: [
1
]
}
Named parameters
raw
supports named parameters, e.g.
sql`
SELECT ${raw(':foo, :bar', {bar: 'BAR', foo: 'FOO'})}
`;
Produces:
{
sql: 'SELECT $1, $2',
values: [
'FOO',
'BAR'
]
}
Named parameters are matched using /[\s,(]:([a-z_]+)/g
regex.
