support showing string value for postgres data source

Open joezhoujinjing opened this issue 6 years ago • 10 comments

Currently it seems only numeric values are support. If the value is string (i.e. varchar), it will not crash but no value is shown.

@ryantxu if it's supported but I somehow missed that, could you kindly point me how to do it? Thanks very much.

I could use this feature too, but for ms sql data sources. I can use string values with influxdb sources already.

Yea, influxdb works for me as well, but I wanted to use redshift, so want to have postgres working as well.

what behavior are you seeing? I am using it with a postgres (google SQL, pretendign to be postres) datasource without issue

Same problem here. Using postgres 10. It says: "Value column must have numeric datatype, column: status type: string value: OK" Wierdly enoug, if I choose my primary key id as metric it says, that it would be able to use a string as a metric name: "Column metric must be of type UNKNOWN, TEXT, VARCHAR, CHAR. metric column name: metric type: INT8 but datatype is int64" Screenshot from 2019-03-18 09-55-23

I've got the same issue with mysql. would be grate if "value" could be a string.

It seems that I am running into the same issue. @ryantxu what extra information do you need?

Without touching to the query, if I "format as table" and use the default table visualization tool, the data is a simple table with a column "time" and another one with strings in it.

It might be a grafana issue, since when I format the query as "time series" and expand the query, it seems that the output is empty:

Is there any chance to have the plugin work with query formatted as table? #40

Having the same problem with MySQL datasource, so have to convert my Values to ints using a case statement... which doesn't make for a very readable graph legend :(

Hi All

I've been banging my head against this lately too. I've found that with current versions of Grafana (ie: 6+), the currently released version of the plugin (0.0.9) doesn't work with strings.

Long story short: build your own v0.0.10-dev version from git master, and you'll get something that works with the latest Grafana.

cheers Ben
