The database table has five columns; 'id aria artist a_artist album_title'. I assume I will use a SELECT * FROM aria_precis WHERE type command.

I want to access all arias that have mio ben within the aria title. In the example below I want to display cbiylm06 and cbiylm10.

cbiylm06#Caro mio ben#Cecilia Bartoli##Se tu m'ami
cbiylm07#Pur dicesti, o bocca bella#Cecilia Bartoli##Se tu m'ami
cbiylm08#Intorno all'idol mio#Cecilia Bartoli##Se tu m'ami
cbiylm09#Nel cor più non mi sento#Cecilia Bartoli##Se tu m'ami
cbiylm10#Il mio ben quando ve#Cecilia Bartoli##Se tu m'ami
cbiylm11#O Leggiadri Occhi Belli#Cecilia Bartoli##Se tu m'ami
cbiylm12#Il mio bel foco#Cecilia Bartoli##Se tu m'ami

Thank you;

Sherman,

In the future, please be kind enough to provide PostgreSQL version and O/S when posting to this listing.

Also include COLUMN HEADERS with all data and present the data formatted so it is easily readable by humans.

Presuming the # is your column divider, and the data you have provided looks like this:
id                #aria                                     #artist                       #a_artist     #album_title
cbiylm06    #Caro mio ben                      #Cecilia Bartoli         #                 #Se tu m'ami
cbiylm07    #Pur dicesti, o bocca bella    #Cecilia Bartoli         #               #Se tu m'ami
cbiylm08    #Intorno all'idol mio               #Cecilia Bartoli         #                 #Se tu m'ami
cbiylm09    #Nel cor più non mi sento      #Cecilia Bartoli        #                 #Se tu m'ami
cbiylm10    #Il mio ben quando ve           #Cecilia Bartoli         #                 #Se tu m'ami
cbiylm11    #O Leggiadri Occhi Belli        #Cecilia Bartoli         #                 #Se tu m'ami
cbiylm12    #Il mio bel foco                      #Cecilia Bartoli         #                 #Se tu m'ami

Then all you really need is:

SELECT *

FROM aria_precis

WHERE aria LIKE '%mio ben%';
