Why Does My SQLite CREATE TABLE Statement Fail with a 'near 'Transaction': syntax error'?

Unidentifiable SQLite Syntax Error: Unraveling the Mystery

In the endeavor to construct a database, a developer encountered an enigmatic error: "Near line 83: near 'Transaction': syntax error." Upon scrutinizing line 83 and its context, the offending command emerged as a CREATE TABLE statement for the "Transaction" table.

Perplexed by the issue, the developer sought assistance, suspecting a potential ASCII issue. However, meticulous re-writing did not resolve the problem. Further investigation revealed that the table name, "Transaction," is a reserved keyword in SQLite.

Reserved Keywords in SQLite

SQLite, similar to many other programming languages, reserves certain keywords for internal use. These keywords are integral to the language's syntax and cannot be utilized for other purposes, such as table or column names. To protect against ambiguity, SQLite mandates that identifiers not be declared using reserved keywords.

Resolving the Issue

To rectify the error, two approaches can be adopted:

1. Renaming the Table: By selecting a non-reserved word for the table name, the conflict with the reserved keyword can be eliminated. This ensures compatibility with SQLite's syntax rules.
2. Quoting the Reserved Name: Alternatively, the reserved name can be encapsulated within quotation marks. SQLite provides four valid quoting options: single quotes ('), double quotes ("), square brackets ([]), and backticks (`). By enclosing the reserved keyword within these delimiters, the syntax error can be circumvented.
