SQL defines two primary character types: character varying(n) and character(n), where n is a positive integer. Both of these types can store strings up to n characters (not bytes) in length. An attempt to store a longer string into a column of these types will result in an error, unless the excess characters are all spaces, in which case the string will be truncated to the maximum length. (This somewhat bizarre exception is required by the SQL standard.) If the string to be stored is shorter than the declared length, values of type character will be space-padded; values of type character varying will simply store the shorter string.
If one explicitly casts a value to character varying(n) or character(n), then an over-length value will be truncated to n characters without raising an error. (This too is required by the SQL standard.)
The notations varchar(n) and char(n) are aliases for character varying(n) and character(n), respectively. If specified, the length must be greater than zero and cannot exceed 10485760. character without length specifier is equivalent to character(1). If character varying is used without length specifier, the type accepts strings of any size. The latter is a PostgreSQL extension.
In addition, PostgreSQL provides the text type, which stores strings of any length. Although the type text is not in the SQL standard, several other SQL database management systems have it as well.
Values of type character are physically padded with spaces to the specified width n, and are stored and displayed that way. However, trailing spaces are treated as semantically insignificant and disregarded when comparing two values of type character. In collations where whitespace is significant, this behavior can produce unexpected results; for example SELECT 'a '::CHAR(2) collate "C"
Read moreI went through the drive through today around 2:50 pm ish and made an order of a hard shell taco and a small Baja blast float. I got to the window paid and the young woman was nice and helpful. However, when she gave me the drink it was not a float. I inquired about it because that is what I ordered and what my child wanted. She seemed a little confused and told me to hang on a second. A few seconds later a, I’m not trying to be rude just descriptive, a heavy set woman with short hair opened the window and represented herself as a manager. She aggressively asked me what my question was. I told her that I thought we had ordered a float. She, again aggressively, told me that the call there floats a freeze. I said ok is there a way that we can correct this. She told me that I could pay for a freeze. I looked at her and asked her why she was being so aggressive. To which she responded in a patronizing tone I’m not being aggressive. I told her I don’t want to fight with her and to have a good day. I understand that we all have had bad days and jobs we do not like. But do not treat me as though I. Have some master plan to steal a scope of ice cream from Taco Bell. I would have Ben happy to pay the difference for the “freeze” and have a scoop of ice cream added to my child’s drink. But don’t come out with some aggressive tone, then hen called out on it passive aggressively act like you are the victim. It is rude, unprofessional,...
Read moreI actually ate here a month ago, but still wanted to shed light on my experience. When I walked into the restaurant it was about 3pm in the afternoon. There were two workers talking out front next to their vehicles and smoking. One of them saw me and went inside to help I imagine. The other just continued to talk on the phone, smoke a cigarette and just stare at me. He was probably on a break, but it was just a weird first impression of the restaurant. So I go in to the restaurant, take my order and then go to find a table and cannot find a single clean table. Now it didn't look like a battleground, but there was evidence of people eating on EVERY table. There were also bits of lettuce and tomato scattered about on the floor. Now it's hard to say what happened before I got there, but being 3pm in the afternoon, and seeing the workers outside doing nothing when I got there, leaves the impression that they were just lazy and did not want to take the time to do the necessary cleaning that the dining area required. Also, the cinnamon sticks were...
