    <p>I would like to find out how a Postgres stored function can return a table, with identified columns. I've used returns setof returnType:</p> <pre><code>-- create employeeSearchResult returnType create type employeeAllReturnType as ( id bigserial, "positionId" integer, "subjectId" bigint, "dateEngaged" date, "nextKin" text, "nrcNo" text, dob date, father text, mother text, wife text, "userId" integer, "statusId" integer, "mainCode" text, "subCode" text ); -- Search for emmployee by name CREATE OR REPLACE FUNCTION "employee_search_by_name"(employeeNameIN text) returns setof employeeAllReturnType as $$ declare results record; resultsRow employee%rowtype; nameIn text; begin nameIn = employeeNameIN || '%'; for results in select employee.id,-- bigserial NOT NULL, employee."positionId",-- integer, employee."subjectId",-- bigint NOT NULL, employee."dateEngaged",-- date, employee."nextKin",-- text, employee."nrcNo",-- text, employee.dob,-- date, employee.father,-- text, employee.mother,-- text, employee.wife,-- text, employee."userId",-- integer NOT NULL, employee."statusId",-- integer, employee."mainCode",-- character(5) NOT NULL, employee."subCode"-- character(10), from employee, subject where employee."subjectId" = subject.id and (subject.name1 ILIKE nameIn OR subject.name2 ILIKE nameIn OR subject.name3 ILIKE nameIn OR subject.name4 ILIKE nameIn) loop return next results; end loop; end; $$ language 'plpgsql'; </code></pre> <p>and also return table():</p> <pre><code>-- Search for emmployee by name CREATE OR REPLACE FUNCTION "employee_search_by_name"(employeeNameIN text) returns table (id bigserial, position integer, subject bigint, date_engaged date, next_kin text, nrc_no text, dob date, father text, mother text, wife text, user_id integer, status_id integer, main_code text, sub_code text) as $$ declare results record; resultsRow employee%rowtype; nameIn text; begin nameIn = employeeNameIN || '%'; for results in select employee.id,-- bigserial NOT NULL, employee."positionId",-- integer, employee."subjectId",-- bigint NOT NULL, employee."dateEngaged",-- date, employee."nextKin",-- text, employee."nrcNo",-- text, employee.dob,-- date, employee.father,-- text, employee.mother,-- text, employee.wife,-- text, employee."userId",-- integer NOT NULL, employee."statusId",-- integer, employee."mainCode",-- character(5) NOT NULL, employee."subCode"-- character(10), from employee, subject where employee."subjectId" = subject.id and (subject.name1 ILIKE nameIn OR subject.name2 ILIKE nameIn OR subject.name3 ILIKE nameIn OR subject.name4 ILIKE nameIn) loop return next results; end loop; end; $$ language 'plpgsql'; </code></pre> <p>But both have outputs in the following formats:</p> <pre><code>"(1,1,1,2011-12-01,Timea,fg1254,1981-12-27,moses,sarada,timea,1,1,"ADM ","1 ")" "(37,3,10,2011-11-11,s,s,2011-11-11,s,s,s,1,1,"OP ","1 ")" </code></pre> <p>Is there anyway in which I can have outputs such as those of a select result from a table?</p> <pre><code>"1";1;1;"2011-12-01";"Timea";"fg1254";"1981-12-27";"moses";"sarada";"timea";1;1;"ADM ";"1 " </code></pre> <p>Such that handling result data from the front end wont require a parser.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
