| * Ported from dbtools-common Service.quoteIdentifier() and AMENDED for QSQL usage | ||
| * Diffs: 1. Space separator does not warrant double quote | ||
| * 2. Lower case letters do not warrant double quote | ||
| * | ||
| * Quotes an identifier based on the following: | ||
| * 1) Any lower/mixed case identifier is quoted | ||
| * 2) Any identifier starting with the quote string is NOT quoted. If it is currently quoted (first/last characters | ||
| * are the quote character) then no quoting is needed, and if it not quoted but contains a quote character, the name is | ||
| * invalid. | ||
| * 3) The string is checked for invalid characters; any invalid characters require the string be quoted. A valid identifier | ||
| * starts with a letter and contains only letters, digits, or one of _$#. Note that the database allows any valid character | ||
| * in the database character set. We by policy use the basic ASCII character set to determine letters. | ||
| * | ||
| * Conflicting requirements: | ||
| * - SYS.DBMS_SQLTUNE.ACCEPT_ALL_SQL_PROFILES composite object names shouldn't be quoted | ||
| * - Bug 20667620: weird column name "NO." should | ||
| * @param s | ||

| // 3) the string is not currently quoted. We will only check the first character for a quote. A quote appearing anywhere | ||
