Standard practice in formatting HTML tables - html

I have a simple table in an HTML page. Nothing special.
The format is as follows:
+++++++++++++++++++++++++++++++++++++++++
+Col1 + Col2 + Col3 + Col4 + Col5 + Col6+
+++++++++++++++++++++++++++++++++++++++++
+ + + + + + +
+ + + + + + +
+ + + + + + +
+ + + + + + +
+ + + + + + +
+ + + + + + +
+++++++++++++++++++++++++++++++++++++++++
All the rows display text but I have the following problem:
If the contents in a row of Col6 are too big, then the row "expands" in 2 lines to fit the contents for that row and as a result the text in other column breaks in 2 lines.
E.g. if Col2 had the text: Some-text-in-here it becomes:
Some-text
in-here
And I don't want that.
How do we solve this issue with arrays so that each column does not get affect by the size of other columns this way?


You can use table-layout: fixed for table in combination with some explicit table width (e.g. width: 100%) to make table cell's widths independent from content width.
You can use white-space: nowrap to prevent line wrapping in an element.

How to remove specific number in string that is in random order?

Lets say that I have data rows that look like this:
+----------------------------+
+ test_table +
+----+--------+--------------+
+ id + word + updated_word +
+----+--------+--------------+
+ 1 + g00gle + ggle +
+ 2 + bread0 + bread +
+ 3 + 0bject + bject +
+ 4 + d0d0 + dd +
+-------------+--------------+
What statement could I use to take out the zeroes in the word column, so that it looks like the updated_word column? I thought of using substring, but didn't know how to proceed after that.

try:
UPDATE test_table
SET word = REPLACE(word, '0', '');
replace the 2nd blank '' with anything you want to change with.

stored procedure for sending email with html table formatting issue

On of the previous developers had a process that sent email alerts in the form of an html table in an email, this was done by triggering an stored procedure and passing the relevant parameters. This is a little outside my skills at the moment but im trying to get the same procedure to send an email for lateness. It works fine bar the formatting and layout. the query is -
SET #xml = CAST(( SELECT td = '<td align = "Center">' + CONVERT(VARCHAR(12),EmployeeName) + '</td>'
, td = '<td align = "Center">' + CONVERT(VARCHAR(12),StartTime) + '</td>'
, td = '<td align = "Center">' + CONVERT(VARCHAR(12),Late) + '</td>'
FROM #tempLateEmail
FOR XML PATH('tr'),TYPE).value('.','NVARCHAR(MAX)'
) AS NVARCHAR(MAX))
The body output is :
SET #body =
N'<style type="text/css">'
+ 'body {font-family: Arial;font-size:12px;} '
+ 'table{font-size:11px; border-collapse:collapse;table-layout: fixed} '
+ 'td{ border:1px solid black; padding:3px;} '
+ 'th{background-color:#F1F1F1;border:1px solid black; padding:3px;}'
+ 'h1{font-weight:bold; font-size:12pt}'
+ 'h2{font-weight:bold; font-size:10pt}'
+ '</style>'
+ '<body style="width:620px; margin:15px;">'
+ '<div style="margin:0 auto; width:300px">'
+ '<h1>Lateness Email on' + ' ' + convert(varchar, getdate(), 103) + '</h1>'
+ '</div>'
+ '<div style="float:left; width:250px">'
+ '<p>The following people appear to have been late today</p> '
+ '</div>'
+ '<div style="float:left; margin-left:20px; width:250px">'
+ '<div style="height:150px; overflow:auto">'
+ '<table width="250px">'
+ '<tr>'
+ '<th width = 100>Employee</th>'
+ '<th width =100>Expected Start Date</th>'
+ '<th width =100>Minutes Late</th>'
+ '</tr>'
+ #xml
+ '</table>'
+ '</div>'
+ '</div>'
+ '<div style="clear:both;"></div>'
+ '</body>'
SET #subject = 'Lateness Email for - ' + convert(varchar, getdate(), 103)
It then outputs them side by side instead of in a table. I understand why its doing it but I can not work out what to do about it. Hope i've provided enough info

as per Rohit Tiwari's comment there was indeed a <tr> missing from the end of the top secion of code -
SET #xml = CAST(( SELECT td = '<td align = "Center">' + CONVERT(VARCHAR(12),EmployeeName) + '</td>'
, td = '<td align = "Center">' + CONVERT(VARCHAR(12),StartTime) + '</td>'
, td = '<td align = "Center">' + CONVERT(VARCHAR(12),Late) + '</td>**<tr>** '
FROM #tempLateEmail
FOR XML PATH('tr'),TYPE).value('.','NVARCHAR(MAX)'
) AS NVARCHAR(MAX))
highlighted the update above.

I just can't manage to make this work under MySQL !
Thanks in advance !

All of the columns used in the joins, where clause and the order by should probably be indexed. You cannot expect any kind of decent performance in any database without indexes. There is nothing very complex about your query, so this is the most likely problem.
Do not return any columns you don't need. For instance why are you returning T_Supr.Suppression when the value will always be nulll based on your where clause?
In mysql you should look at the Explain Plan to see where the problem is with a slow query. In SQL Server look at the Execution PLan. You need to learn how to read these to effectively program in SQL.

Any idea how to do it?
Note : I don't have any row who have data for all fields. And I don't have any user with below scenario.

+ id + field1 + field2 +

Only 1 data in one row and two row per user.
I tried with
SELECT id, concat(field1), concat(field2) from myTable
GROUP BY id;
but its not coming.

You need to use one of MySQL's aggregate functions when aggregating grouped data. Either use GROUP_CONCAT() in place of (the non-aggregate string function) CONCAT(), or else (better for numeric data) use SUM():
SELECT id, SUM(field1), SUM(field2) FROM myTable GROUP BY id

Note : I don't have any row who have data for all fields. Only 1 data in one row and two or more rows per user.
I tried with
SELECT id, GROUP_CONCAT(MAX(field1)), GROUP_CONCAT(MAX(field2)) from myTable

but its giving error as
Invalid use of group function:

This question is bit advanced to my earlier question, showing data in one row (from multiple rows)

SELECT id, MAX(field1), MAX(field2) FROM myTable GROUP BY id;

This simple query should do the trick.
SELECT id, MAX(field1), MAX(field2)
FROM myTable
GROUP BY id;
it groups all the rows with the same id and selects the maximum value within each group for each column
