Data types and ranges for Microsoft Access, MySQL and SQL Server. At first glance they seem to.

CAST and CONVERT (Transact- SQL)Date and Time Styles. When expression is a date or time data type, style can be one of the values shown in the following table. Other values are processed as 0. SQL Server supports the date format in Arabic style by using the Kuwaiti algorithm. Without century (yy) (1)With century (yyyy)Standard. Input/Output (3)- 0 or 1.

Ideally, it is better to compare Text and Varchar(MAX) data types, as in Sql Server 2005 Varchar(MAX) data type was introduced as an alternate for Text data type. SQL Server Books Online Reference. For more information about SQL Server data.

Input when you convert to datetime; output when you convert to character data. Designed for XML use. For conversion from datetime or smalldatetime to character data, the output format is as described in the previous table.

Hijri is a calendar system with several variations. SQL Server uses the Kuwaiti algorithm. Important. By default, SQL Server interprets two- digit years based on a cutoff year of 2. That is, the two- digit year 4. Many client applications, such as those based on Automation objects, use a cutoff year of 2. SQL Server provides the two digit year cutoff configuration option that changes the cutoff year used by SQL Server and allows for the consistent treatment of dates. We recommend specifying four- digit years.

Only supported when casting from character data to datetime or smalldatetime. When character data that represents only date or only time components is cast to the datetime or smalldatetime data types, the unspecified time component is set to 0. The optional time zone indicator, Z, is used to make it easier to map XML datetime values that have time zone information to SQL Server datetime values that have no time zone. Z is the indicator for time zone UTC- 0. Other time zones are indicated with HH: MM offset in the + or - direction. For example: 2. 00.

T2. 3: 4. 5: 1. 2- 0. When you convert to character data from smalldatetime, the styles that include seconds or milliseconds show zeros in these positions. You can truncate unwanted date parts when you convert from datetime or smalldatetime values by using an appropriate char or varchar data type length. When you convert to datetimeoffset from character data with a style that includes a time, a time zone offset is appended to the result. Styles. When expression is float or real, style can be one of the values shown in the following table.

Other values are processed as 0. Value. Output. 0 (default)A maximum of 6 digits.

Use in scientific notation, when appropriate. Always 8 digits. Always use in scientific notation. Always 1. 6 digits. Always use in scientific notation. Included for legacy reasons and might be deprecated in a future release.

Styles. When expression is money or smallmoney, style can be one of the values shown in the following table. Other values are processed as 0. Value. Output. 0 (default)No commas every three digits to the left of the decimal point, and two digits to the right of the decimal point; for example, 4. Commas every three digits to the left of the decimal point, and two digits to the right of the decimal point; for example, 3,5. No commas every three digits to the left of the decimal point, and four digits to the right of the decimal point; for example, 4. Equivalent to style 2 when converting to char(n) or varchar(n)xml Styles.

When expression is xml, style can be one of the values shown in the following table. Other values are processed as 0. Value. Output. 0 (default)Use default parsing behavior that discards insignificant white space and does not allow for an internal DTD subset.

Preserve insignificant white space. This style setting sets the default xml: space handling to behave the same as if xml: space=.

Enable limited internal DTD subset processing. If enabled, the server can use the following information that is provided in an internal DTD subset to perform nonvalidating parse operations. Genuine Windows Xp License Keys Wga Crack Zip Password on this page.

Defaults for attributes are applied. Internal entity references are resolved and expanded. The DTD content model will be checked for syntactical correctness. The parser will ignore external DTD subsets. It also does not evaluate the XML declaration to see whether the standalone attribute is set yes or no, but instead parses the XML instance as if it is a stand- alone document.

Preserve insignificant white space and enable limited internal DTD subset processing. Binary Styles. When expression is binary(n), varbinary(n), char(n), or varchar(n), style can be one of the values shown in the following table. Style values that are not listed in the table return an error. Value. Output. 0 (default)Translates ASCII characters to binary bytes or binary bytes to ASCII characters. Each character or byte is converted 1: 1. If the data. The expression must be composed of an even number of hexadecimal digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, a, b, c, d, e, f). If the style is set to 1 the characters 0x must be the first two characters in the expression.

If the expression contains an odd number of characters or if any of the characters are invalid an error is raised. If the length of the converted expression is greater than the length of the data. Each binary character is converted into two hexadecimal characters. If the length of the converted expression is greater than the data. Explicit conversions are those conversions that require the CAST or CONVERT function to be specified. The following illustration shows all explicit and implicit data type conversions that are allowed for SQL Server system- supplied data types. These include xml, bigint, and sql.

There is no implicit conversion on assignment from the sql. For example, the following conversion does not return a hexadecimal value of 4. SELECT CAST(CAST(0x. AS nvarchar) AS varbinary). Large- Value Data Types. Large- value data types exhibit the same implicit and explicit conversion behavior as their smaller counterparts, specifically the varchar, nvarchar and varbinary data types. However, you should consider the following guidelines: Conversion from image to varbinary(max) and vice- versa is an implicit conversion, and so are conversions between text and varchar(max), and ntext and nvarchar(max).

Conversion from large- value data types, such as varchar(max), to a smaller counterpart data type, such as varchar, is an implicit conversion, but truncation will occur if the large value is too big for the specified length of the smaller data type. Conversion from varchar, nvarchar, or varbinary to their corresponding large- value data types is performed implicitly. Conversion from the sql. Large- value data types cannot be converted to the sql. For information about how to convert Microsoft . NET Framework common language runtime (CLR) user- defined types, see Performing Operations on User- defined Types.

For more information about how to convert from the xml data type, see Generating XML Instances. Data Type. When you explicitly or implicitly cast the xml data type to a string or binary data type, the content of the xml data type is serialized based on a set of rules. For information about these rules, see Serialization of XML Data. For information on how to cast from XML to a CLR user- defined type, see Performing Operations on User- defined Types. For information about how to convert from other data types to the xml data type, see Generating XML Instances.

Oracle Data Types - Oracle Data types for Oracle 8 to Oracle 1. Datatype. Description. Max Size: Oracle 8. Max Size: Oracle 9i/1. Max Size: Oracle 1. Max Size: PL/SQL PL/SQLSubtypes/ Synonyms VARCHAR2(size)Variable length character string having maximum length size.

If you create a column as. Varchar. 2 (5. 0) but only store 1. Oracle will only save 1.

Integer NUMBERNUMBER(p)This is a fixed- point number with precision p and scale 0. Equivalent to NUMBER(p,0). Floating- Point NUMBERNUMBERfloating- point number with decimal precision 3. PRECISION and SCALEOracle stores all numeric data in variable length format - storage space is therefore dependent on the length of all the individual values stored in the table. Precision and scale settings do not affect storage requirements. SCALE might appear to be truncating data, but Oracle does still store the entire number as typed.

PRECISION can be used to constrain input values. If a column is defined like CREATE TABLE demo ( empid number(4) ); then an attempt to insert a 5 digit number 1. This would have to be done at the application level.

If a table is created without any Precision/Scale CREATE TABLE demo ( empid number ); then the column will simply store values as given. When no scale is specified, the scale is zero.

Function parameters. Oracle does not allow a specific precision for function parameters, only type of the variable. This means that a parameter defined as integer or number(3. Alternatively reassigning to a variable within the procedure will force Oracle to implicitly convert the datatype and precision to match the variable, thie requires a slightly different definition, e.

Storing Y and N requires no more (but also no less) than storing 0 and 1 but saves you the effort of writing a decode statement to display it. Of course if/when the application has to support other languages then you will need to add the decode anyway.
