sql - Restrict column name changes/creation to not allow specific characters -

-

currently characters used in column names break external programs, i'm looking way restrict specific characters ("." "_" etc) being used, either creation of new columns, or editing existing ones.

for example, if user tried create column "random_info", automatically rename "randominfo", , same goes editing existing column: remove offending characters before change made.

the issue might create duplicate columns, i'm not sure best course of action handle though.

it seems triggers might need, i've got them working editing actual content of columns, not change column name itself.

a bit stuck on 1 , google has failed me, i've provided enough information give answer here!

Listeners to visualise results of load test in JMeter -

-
i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
