    <p>I have multiple records of the structure in the 'column1' column that I want to update the type in the same column.</p> <p>These fields contain information about the language, categories level and name, in only one FIELD.</p> <p>Information is separated by symbols as follows:</p> <ol> <li>" : " (two points) separating language by root( language% : Top/% )</li> <li>" / " ( Slash ) separating root ( Top / level_1) by category, and category (level_1 / level_2 ) by different level category.</li> <li>So the FIELD will have the following form "language:Top/level/level"</li> </ol> <p>Information stored on FIELDS comes from two different sources one is internal and the other FIELDS without root( Top/ ) come from an external source and must be updated by SQL</p> <p>Real example field:</p> <p><strong>before</strong></p> <p>&amp;lt;b&amp;gt;Englisch&amp;lt;/b&amp;gt;:level/Test/later</p> <p><strong>after</strong></p> <p>&amp;lt;b&amp;gt;Englisch&amp;lt;/b&amp;gt;:Top/level/Test/later</p> <p>Real example table:</p> <pre><code>**before** **after** language0:Top/level_0/name_category language0:Top/level_1/name_category language1:name_test2/name_category language1:name_test2/name_category language2:level_1/name_category language2:Top/level_1/level_2/name_category language3:level_1/level_2/name_category language3:Top/level_1/level_2/name_category language4:level_1/level_2/level_3/name_category language4:Top/level_1/level_2/level_3/name_category </code></pre> <p>first line have already changed so we need to SELECT only those record that start with "language%:level_1/%" </p> <p><strong>table_example1</strong></p> <pre><code>id **column1** 1 language0:Top/level_1/level_2/level_3/level_4 2 language1:name_test2/etc/ 3 language2:level_1/level_2/level_3/level_4 4 language3:level_1/level_2/level_3 5 language3:level_1/level_2 6 language%:level_1/ </code></pre> <p>Note: </p> <ul> <li>Only these fields must be updated in the example: line id 3,4,5,6 and only column1 in the table</li> <li>The results must be like line id 1 column1: <code>language0:Top/name_test/etc/etc/</code>.</li> <li>The field <code>language1:name_test2/etc/</code> in line id 2 column1 will be ignored is diferent format and stored diferent information.</li> <li>Basis for not changing line 2 is different link value: name_test2(name_test) LIKE 'name_test/%' only</li> <li>this # symbol not exist in the field is only to delineate you can see before column, after column</li> <li>The FIELD should be updated only if after the following two points ( : )there is exactly the expression followed by the slash (level_1/)</li> </ul> <p>Other records that start otherwise must not be modified.</p> <p>How can I do this?</p>

    1. COWhat is the basis for not changing line 2? Is it that there is no hash `#` symbol after the colon `:`? So, is the requirement to change `:#` into `:Top/`? If so, then the tabular 'From' column needs to be revised, though I took what you had written out verbatim to make that mapping table.

    2. CORephrase the note. Line 6 does not include even language. Please clarify your criteria. If you had completed your question before `table_example1`, then it was clear

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).
