Tracking issue for typos in current partiql specification

[alancai98]

While porting some tests from the PartiQL specification to the conformance test repo, partiql-tests, I noticed some typos in the examples. Below lists some of the encountered typos:

• Example 8 -- can't use a keyword as an identifier. Resolution is to either use double quotes around symbol (which loses case-insensitivity) or change the name of symbol
• Example 10 -- quotes missing around the v binding
• Example 11 -- missing comma after first line of readings in initial environment
• Example 18, 19, 20, 21 -- for each of these examples, missing the v alias in the FROM sources
• Example 22 -- similar to "Example 8"; can't use keyword symbol as identifier without double quotes
• Example 26 -- the result should be in a bag not an array
• Example 29 -- {’a’:1, ’b’:2} = {’a’:1} repeated example
• Example 30 -- should be SELECT VALUE rather than SELECT VALUES
• following Example 40 on page 38 -- GROUPY -> GROUP BY
• Example 44 -- SELECT aliases for avg and count need double quotes since they are keywords
• Example 47 -- in globals, TIMESTAMP value constructor syntax not supported. Perhaps the TIME constructor syntax is intended here? -- tracking in PartiQL spec example 47 (section 11.3) unspecified timestamp syntax #72
• Example 49 -- missing FROM source alias x

PIVOT x.v AT x.a
FROM << {'a': 'first', 'v': 'john'}, {'a': 'last', 'v': 'doe'} >> AS x

Other typos:

• Inconsistent single quotation markings in the examples -- using ’ rather than ' (the former is not parseable), which made it harder to copy and paste examples from the specification
• Inconsistent bag operator in examples << ... >>. Not as annoying since they copy and pasted the same
• "An PartiQL ..." rather than "A PartiQL"

Feel free to comment any other errors/typos encountered, and I will update the issue.
