charColumn

Defines a nullable CHAR(1) column in the table, intended to store a single Char.

This function creates and registers a column with the type CHAR(1). KQLite will handle the conversion between a single-character string in the database and a Kotlin Char type in your application. The column is nullable by default.

Important: Stored value in this column must either be NULL or exactly one character.

Example:

object UserProfiles : KQLiteTable("user_profiles") {
    // A nullable CHAR(1) column for a user's initial
    val middleInitial = charColumn("middle_initial")

    // A non-null column for a status code (e.g., 'A' for Active, 'I' for Inactive)
    val status = charColumn("status").notNull().default('A')
}
