    <p>Search your hard drive for a file called bde32.hlp that is installed with Borland Delphi. It is a Windows Help file that contains a documentation of the BDE API. It also contains a topic titled "Binding external schema to text tables" which describes the format of the *.sch files.</p> <p>Under the title "Language drivers", the same help file also contains a list of "short names" that can be specified for the <code>CharSet</code> entry in the *.sch file.</p> <p>So, for example, if you want to use the Windows character set for west european languages (Windows-1252), that you will need for French accented characters or German umlauts, the value to use for <code>CharSet</code> is <code>ANSIINTL</code> like that:</p> <pre><code>[CUSTOMER] Filetype=VARYING Delimiter=" Separator=, CharSet=ANSIINTL </code></pre> <hr> <blockquote> <p>What encoding(s) can be used for the .sch file itself? (This is relevant for correctly interpreting the fieldnames and other configurable characters.)</p> </blockquote> <p>Just plain ASCII. There is no scenario that would require or allow you to use anything but good old ASCII characters with character codes from 0-127 and of those (except for line breaks to separate the different lines) only printable characters are meaningful.</p> <p>For example, no other characters (umlauts, accented chars, etc) are allowed in the table name or column names.</p> <blockquote> <p>How should I specify non-printable Separator and Delimiter characters, for example an Ansi control-character like "Unit Separator" ($1F) or even a simple "Tab" ($09)? (Given the age of the format I think I should use Caret notation, but it'd just like to be sure.)</p> </blockquote> <p>Not possible. Only "visible" characters can be used as delimiter and separator. To use a tab, just use an empty assignment:</p> <pre><code>[CUSTOMER] Filetype=VARYING Delimiter=" Separator= CharSet=ANSIINTL </code></pre> <blockquote> <p>How can I specify to not-use a Delimiter? Should I specifiy an empty value, or leave the setting out altogether?</p> </blockquote> <p>In "Fixed" format, no separators and no delimiters are used. In "Varying" format, a delimiter is always used for columns with string/character type and a delimiter is never used for other column types. To not use a delimiter, just use an empty assignment in the schema:</p> <pre><code>[CUSTOMER] Filetype=VARYING Delimiter= Separator=, CharSet=ANSIINTL </code></pre>

    1. COThanks, your reference to the "Language drivers" topic anwers my question on the "CharSet" setting. I can't find much details on specifying the other settings tho...

    2. COThe help topic in BDE32.hlp is the official documentation. There is nothing that is more detailed. I think, it is pretty much straight forward and self explanatory. What question is still unclear?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
