Is it possible to divide all columns in a table by one of them? There are 168 of them so I'd rather not write column2/column1, column3/column1, etc.
As Suggested by #Aishwary, you can write a script to get the list of columns using INFORMATION_SCHEMA and then iterate over the list of columns to get the desired result.

IS there a way in SQL to make multiple rows for a common column, show up in one?
For example I would like this output:
to show up as:
I believe this article contains solutions to your question -
SQL Query to concatenate column values from multiple rows in Oracle
I have a column of type string in my table, where multiple values are separated by pipe operator. For example, like this,
Value1|Value2|Value3
Now, what I want is to have a query, which will show three rows for this row. Basically something similar to the concept of explode in Dataframes.
Note that I am using Spark SQL. And I want to achieve this using SQL, not dataframes.
I got it working by using the following query.
select t.*, explode(split(values, "\\|")) as value
from table t
\\| here can also be replaced by [|]. Just specifying | doesn't work.
Im trying to make a table with dynamic columns.
I have this table. This is just simplified, in other instances these may have more values instead of 3.

I am trying to get this result. I need to separate the values into columns.
Fall | Medication | Wander

You need to PIVOT the table. Unfortunately MySQL (unlike Oracle http://www.oracle.com/technetwork/articles/sql/11g-pivot-097235.html) doesn't have a PIVOT operator, but there are workarounds it seems. MySQL pivot table
You might try one of the crosstab() functions in newer PostgreSQL. See https://www.postgresql.org/docs/current/static/tablefunc.html (F.35.1.2 and F.35.1.4). It allowes you to specify a query that has row-names (those create rows), categories (that create columns) and values (that populate the inside part of the table.
The variant with 2 queries can be especially useful since it allows you to specify the columns you want to use with a seperate query.
I am using PyODBC to fetch some data, since I am not fetching all data in my table, I need to write a query which grabs only rows which have associated columns. For example my initial query is:
SELECT SRNumber FROM SO_SC_1 WHERE SRNumber LIKE '%1-%'
This returns the SRNumber values that I want.
Next I want to return the associated last edited user with this SRNumber. This column is named last_edited_user. What is the proper syntax to incorporate multiple queries into one for this scenario? Basically I would like to use the initial query and grab all associated data for each SRNumber.
You query all needed columns using their comma separated names
SELECT SRNumber, last_edited_user
FROM SO_SC_1
WHERE SRNumber LIKE '%1-%'
I have a requirement to display row values as column names in a data grid view. I want to get the store names into columns using sql select statement. (Please refer the attached image). I want user to enter some values under each column. So STORE 1, STORE 2, STORE 3 should displays as columns in datagrid view. Does anyone can help me to get this work?
while googling i found this can be done using PIVOT in SQL. But in this table i don't have any aggregate columns. Any help pls?
the result should be somthing like
You may know that your data only contains a single row for each pivoting column, but SQL Server has to construct a plan that could accommodate multiple rows.
So, use PIVOT and just use an aggregate that, if passed a single value, will return that same value. MIN() and MAX() fit that description (as does SUM if you're working with numeric data)
You may use specific function of dynamic pivot and pass your query with item count column.
You can use below link which provided you function and can easily show you expected output.
