ASCII

Keyword ASCII

SQL command to get ASCII value of first char.

Please be aware that AlaSQL uses Javascript to find the char values. The traditional ASCII chars are all OK, but 25 of the extended ASCII table will give different result than expected in traditional DBs

The following chars gives a different value than expected (here the expected value is shown)

    - SELECT ASCII('€'); -- 128 - Euro sign
    - SELECT ASCII('‚'); -- 130 - Single low-9 quotation mark
    - SELECT ASCII('ƒ'); -- 131 - Latin small letter f with hook
    - SELECT ASCII('„'); -- 132 - Double low-9 quotation mark
    - SELECT ASCII('…'); -- 133 - Horizontal ellipsis
    - SELECT ASCII('†'); -- 134 - Dagger
    - SELECT ASCII('‡'); -- 135 - Double dagger
    - SELECT ASCII('ˆ'); -- 136 - Modifier letter circumflex accent
    - SELECT ASCII('‰'); -- 137 - Per mille sign
    - SELECT ASCII('Š'); -- 138 - Latin capital letter S with caron
    - SELECT ASCII('‹'); -- 139 - Single left-pointing angle quotation
    - SELECT ASCII('Œ'); -- 140 - Latin capital ligature OE
    - SELECT ASCII('Ž'); -- 142 - Latin captial letter Z with caron
    - SELECT ASCII('“'); -- 147 - Left double quotation mark
    - SELECT ASCII('”'); -- 148 - Right double quotation mark
    - SELECT ASCII('•'); -- 149 - Bullet
    - SELECT ASCII('–'); -- 150 - En dash
    - SELECT ASCII('—'); -- 151 - Em dash
    - SELECT ASCII('˜'); -- 152 - Small tilde
    - SELECT ASCII('™'); -- 153 - Trade mark sign
    - SELECT ASCII('š'); -- 154 - Latin small letter S with caron
    - SELECT ASCII('›'); -- 155 - Single right-pointing angle quotation mark
    - SELECT ASCII('œ'); -- 156 - Latin small ligature oe
    - SELECT ASCII('ž'); -- 158 - Latin small letter z with caron
    - SELECT ASCII('Ÿ'); -- 159 - Latin capital letter Y with diaeresis

The return value is based on unicode. In the following you can see what is normally expected and what the library will return:
