avoid duplicate comment opts

[sunary]

Summary by CodeRabbit

• Bug Fixes
  • Resolved an issue where multiple comment options could be included in SQL definitions; now only the first comment is retained.
  • Improved comparison logic for column options to ignore any options appearing after a comment, ensuring more accurate detection of changes.

Walkthrough

The changes update logic in the Column struct and related table comparison functions to ensure that only the first column comment is processed and that column option comparisons disregard any options appearing after the first comment. This adjustment affects how SQL definitions and option comparisons are generated and evaluated internally.

Changes

Cohort / File(s)	Change Summary
Column Option Comment Handling element/column.go	Updated the pkDefinition method to track and include only the first column comment option when generating SQL, skipping subsequent comments.
Column Option Comparison Logic element/table.go	Modified hasChangedMysqlOptions to filter out column options after the first comment before comparing option lists, ensuring only relevant options are considered.

Poem

A bunny hops with code so neat,
Filtering comments, skipping repeat.
Only the first one gets to stay,
The rest are gently swept away.
Options compared with careful care,
Now column changes are more fair!

element/column.go (2)

189-189: LGTM: Proper initialization of comment tracking flag.

The hasComment boolean flag is correctly initialized to track when the first comment option is encountered.

---

253-259: LGTM: Correct implementation of duplicate comment prevention.

The logic properly ensures that:

1. Options are only appended to the SQL string when hasComment is false
2. The flag is set to true after encountering the first ColumnOptionComment
3. This prevents duplicate comment options from being included in the SQL definition

This implementation aligns with the PR objective of avoiding duplicate comment options.

element/table.go (3)

265-286: LGTM: Correct filtering logic to exclude options after first comment.

The filtering logic properly:

1. Creates new slices to store options before the first comment
2. Uses a hasComment flag to track when to stop adding options
3. Applies the same filtering to both new and old option slices

This ensures consistent handling with the changes in element/column.go.

---

287-287: LGTM: Correct length comparison using filtered options.

The length comparison now uses the filtered option slices optNew and optOld, which is consistent with the filtering approach.

---

297-299: LGTM: Correct variable usage for old options map.

The mOld map correctly uses optOld for both iteration and map assignment.
