This commit fixes/adds tests for and fixes several issues with `JOIN`
operator parsing:
- For OUTER joins, LEFT | RIGHT | FULL specifier is not optional
```nim
doAssertRaises(SqlParseError): discard parseSql("""
SELECT id FROM a
OUTER JOIN b
ON a.id = b.id
""")
```
- For NATURAL JOIN and CROSS JOIN, ON and USING clauses are forbidden
```nim
doAssertRaises(SqlParseError): discard parseSql("""
SELECT id FROM a
CROSS JOIN b
ON a.id = b.id
""")
```
- JOIN should parse as part of FROM, not after WHERE
```nim
doAssertRaises(SqlParseError): discard parseSql("""
SELECT id FROM a
WHERE a.id IS NOT NULL
INNER JOIN b
ON a.id = b.id
""")
```
- LEFT JOIN should parse
```nim
doAssert $parseSql("""
SELECT id FROM a
LEFT JOIN b
ON a.id = b.id
""") == "select id from a left join b on a.id = b.id;"
```
- NATURAL JOIN should parse
```nim
doAssert $parseSql("""
SELECT id FROM a
NATURAL JOIN b
""") == "select id from a natural join b;"
```
- USING should parse
```nim
doAssert $parseSql("""
SELECT id FROM a
JOIN b
USING (id)
""") == "select id from a join b using (id );"
```
- Multiple JOINs should parse
```nim
doAssert $parseSql("""
SELECT id FROM a
JOIN b
ON a.id = b.id
LEFT JOIN c
USING (id)
""") == "select id from a join b on a.id = b.id left join c using (id );"
```
This directory contains the test cases.
Each test must have a filename of the form: t*.nim
Note: Testament is only aware of tests under a directory (eg tests/foo/) and will ignore
top-level tests like tests/tbar.nim.
Specs
Each test can contain a spec in a discard """ ... """ block.
Check out the parseSpec procedure in the specs module for a full and reliable reference
action
Specifies what action this test should take.
Default: run
Options:
compile- compiles the module and fails the test if compilations fails.run- compiles and runs the module, fails the test if compilation or execution of test code fails.reject- compiles the module and fails the test if compilation succeeds.
There are certain spec keys that imply run, including output and
outputsub.
Categories
Each folder under this directory represents a test category, which can be
tested by running koch tests pcat <category> (or cat to avoid parallel
testing, which is slower).
The folder dll contains simple DLL tests.
The folder realtimeGC contains a test for validating that the realtime GC
can run properly without linking against the nimrtl.dll/so.
