SQL syntax incorrectly capitalized "SQL" when it's a lowercase column name

[gfairchild]

http://www.gfairchild.com/2012/08/03/how-to-rename-columns-in-an-sqlite-database/ shows the example in practice. Here's the chunk of code to be highlighted:

BEGIN; --start a transaction; this ensures that your changes won't be written until you COMMIT
.schema --this will show you your current schema
PRAGMA writable_schema=1; --this enables you to edit the schema
SELECT * FROM sqlite_master; --show the raw data SQLite saves related to your schema
UPDATE sqlite_master SET sql=replace(sql, 'county', 'county_id') WHERE name='people'; --simple string replace
.schema --verify CREATE TABLE is correct
UPDATE sqlite_master SET sql='CREATE INDEX people_county_id_index on people(county_id)' WHERE name='people_county_index'; --update index SQL
UPDATE sqlite_master SET name='people_county_id_index' WHERE name='people_county_index'; --update index name
.schema --verify index is correct
SELECT * FROM sqlite_master; --double-check all raw data once more
PRAGMA writable_schema=0; --disable editing the schema
COMMIT; --save the changes to the database
.exit

The important thing to note here is what's on line 5:

UPDATE sqlite_master SET sql=replace(sql, 'county', 'county_id') WHERE name='people'; --simple string replace

Here's the output WP-Syntax creates:

BEGIN; --start a transaction; this ensures that your changes won't be written until you COMMIT
.schema --this will show you your current schema
PRAGMA writable_schema=1; --this enables you to edit the schema
SELECT * FROM sqlite_master; --show the raw data SQLite saves related to your schema
UPDATE sqlite_master SET SQL=REPLACE(SQL, 'county', 'county_id') WHERE name='people'; --simple string replace
.schema --verify CREATE TABLE is correct
UPDATE sqlite_master SET SQL='CREATE INDEX people_county_id_index on people(county_id)' WHERE name='people_county_index'; --update index SQL
UPDATE sqlite_master SET name='people_county_id_index' WHERE name='people_county_index'; --update index name
.schema --verify index is correct
SELECT * FROM sqlite_master; --double-check all raw data once more
PRAGMA writable_schema=0; --disable editing the schema
COMMIT; --save the changes to the database
.exit

Notice how in line 5, all instances of sql are now capitalized. Here, sql is a lowercase column name and should remain lowercase when WP-Syntax renders it.
