You'll use psql (aka the PostgreSQL interactive terminal) most of all because it's used to create databases and tables, show information about tables, and even to enter information (records) into the database.. SQL Server The table will be owned by the user issuing the command. Column definitions follow this syntax pattern: column_name data_type (optional_data_length_restriction) column_constraints. Usually you can run the following command to enter into psql: psql DBNAME USERNAME For example, psql template1 postgres. If you see anything in the documentation that is not correct, does not match The following are nonstandard extensions: The standard requires parentheses around the subquery clause; in PostgreSQL, these parentheses are optional. For example, we might want to ensure that every user in our database has a unique id, so we could use the UNIQUE constraint.. Informix CREATE TABLE AS creates a table and fills it with data computed by a SELECT command. If this option is not specified, the default table access method is chosen for the new table.

We’ll use the command shown below: In contrast, a view re-evaluates its defining SELECT statement whenever it is queried. Enum types are created using the CREATE TYPE command, for example: CREATE TYPE mood AS ENUM ('sad', 'ok', 'happy'); Once created, the enum type can be used in table and function definitions much like any other type: "),c=g;a[0]in c||!c.execScript||c.execScript("var "+a[0]);for(var e;a.length&&(e=a.shift());)a.length||void 0===d?c[e]?c=c[e]:c=c[e]={}:c[e]=d};function l(b){var d=b.length;if(0=d.offsetWidth&&0>=d.offsetHeight)a=!1;else{c=d.getBoundingClientRect();var f=document.body;a=c.top+("pageYOffset"in window?window.pageYOffset:(document.documentElement||f.parentNode||f).scrollTop);c=c.left+("pageXOffset"in window?window.pageXOffset:(document.documentElement||f.parentNode||f).scrollLeft);f=a.toString()+","+c;b.b.hasOwnProperty(f)?a=!1:(b.b[f]=!0,a=a<=b.g.height&&c<=b.g.width)}a&&(b.a.push(e),b.c[e]=!0)}p.prototype.checkImageForCriticality=function(b){b.getBoundingClientRect&&q(this,b)};h("pagespeed.CriticalImages.checkImageForCriticality",function(b){n.checkImageForCriticality(b)});h("pagespeed.CriticalImages.checkCriticalImages",function(){r(n)});function r(b){b.b={};for(var d=["IMG","INPUT"],a=[],c=0;c=a.length+e.length&&(a+=e)}b.i&&(e="&rd="+encodeURIComponent(JSON.stringify(t())),131072>=a.length+e.length&&(a+=e),d=!0);u=a;if(d){c=b.h;b=b.j;var f;if(window.XMLHttpRequest)f=new XMLHttpRequest;else if(window.ActiveXObject)try{f=new ActiveXObject("Msxml2.XMLHTTP")}catch(k){try{f=new ActiveXObject("Microsoft.XMLHTTP")}catch(v){}}f&&(f.open("POST",c+(-1==c.indexOf("?")?"?
