Fix incorrect default param types for mssql, oracle, and sqlite#87
Fix incorrect default param types for mssql, oracle, and sqlite#87
Conversation
- mssql: change named prefix from ':' to '@' (T-SQL uses @name, not :name) - oracle: add named [':'] and numbered [':'] (OCI/node-oracledb use :name and :N) - sqlite: add '$' to named prefixes ($name is natively supported by SQLite) Update all affected tests to match the corrected syntax. Fixes #55 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
T-SQL supports both @name (native) and :name (common in ORMs/drivers). Add ':' to mssql named prefixes and add tests for colon-style params. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Pull request overview
This PR fixes incorrect default parameter type configurations for three SQL dialects (MSSQL, Oracle, and SQLite) to align with their actual parameter syntax conventions.
Changes:
- MSSQL: Changed primary parameter prefix from
:to@(T-SQL standard), while maintaining:for backward compatibility - Oracle: Added explicit support for
:namenamed parameters and:Nnumbered parameters (previously fell through to generic positional-only mode) - SQLite: Added support for
$nameparameter syntax (completing support for all 5 SQLite parameter forms)

| File | Description |
|---|---|
| src/parser.ts | Updated defaultParamTypesFor() to return correct parameter prefixes for mssql (['@', ':']), oracle (: for both named and numbered), and sqlite (added $ to named prefixes) |
| test/tokenizer/index.spec.ts | Updated mssql tests to use @ prefix, removed mssql from numbered parameter test, added new tests for mssql @ parameters, oracle :name parameters, and sqlite $name parameters |
| test/parser/single-statements.spec.ts | Updated mssql parameter extraction tests to use @foo and @bar instead of :foo and :bar |
| test/index.spec.ts | Modified double-colon regression test to verify :: doesn't produce colon-prefixed parameters (while allowing valid @ parameters to be detected) |
| test/identifier/single-statement.spec.ts | Updated mssql tests to use @ prefix, corrected CREATE_FUNCTION test to expect detected @ parameters, added new tests for mssql colon-prefixed parameters (backward compatibility), oracle named/numbered parameters, and sqlite $name parameters |

This seems like a bug to me, since they're not parameters that the user would need to fill in. We can at least detect variables within a function/body by checking if the preceding token is DECLARE, though I'm a bit of a loss for dealing with function parameters.

| expect(res.parameters.every((param) => !param.startsWith(':'))).to.equal(true); |

Feels like can rework the this test to then only do identify('SET @g = geometry::STGeomFromText('POLYGON((0 0, 2 0, 2 2, 0 2, 0 0))', 0);') if just checking that cast isn't parsed to a parameter.
However, similar to above, would be good to think about how we should handle these parameters here.
