A tinyint with a value of 200 returns 127. Usage notes: For a convenient and automated way to check the bounds of the TINYINT type, call the functions MIN_TINYINT() and MAX_TINYINT(). If an integer value is too large to be represented as a TINYINT, use a SMALLINT instead.

Data-wise, tinyint(1), tinyint(2), tinyint(3) etc. are all exactly the same. They are all in the range -128 to 127 for SIGNED or 0-255 for UNSIGNED.As other answers noted the number in parenthesis is merely a display width hint. You might want to note, though, that application=wise things may look different.

In computer science, an integer is a datum of integral data type, a data type that represents some range of mathematical integers.Integral data types may be of different sizes and may or may not be allowed to contain negative values. Integers are commonly represented in

Feb 19, 2013 · Not only is int not more efficient than tinyint or smallint, int is less efficient. That’s because smaller datatypes mean you get more rows per 8K page in your table/clustered index, and if that data element is a key in an index, you get more index entries per page.

SmallInt/TinyInt vs Regular Integer. Smaller types take less space so more rows fit in a page resulting in less space taken both on disk and in memory. Of course, if you choose too small a type your application will fail. Consider also BIGINT for when values larger than 2,147,483,648 (or smaller than -2,147,483,647) might be needed.

[a] The value of BufferLength is ignored for this conversion. The driver assumes that the size of *TargetValuePtr is the size of the C data type. [b] This is the size of the corresponding C data type. [c] This conversion is supported only for the exact numeric data types (SQL_DECIMAL, SQL_NUMERIC, SQL_TINYINT, SQL_SMALLINT, SQL_INTEGER, and SQL_BIGINT).

Here we will see how to convert bool to int equivalent in C++. Bool is a datatype in C++, and we can use true or false keyword for it. If we want to convert bool to int, we can use typecasting. Always true value will be 1, and false value will be 0

int 数据类型是 SQL Server 2005 中的主要整数数据类型。 bigint 数据类型用于整数值可能超过 int 数据类型支持范围的情况。. 在数据类型优先次序表中,bigint 介于 smallmoney 和 int 之间。. 只有当参数表达式为 bigint 数据类型时,函数才返回 bigint。

Instead, TINYINT columns should be fetched into 2-byte or 4-byte integer columns. Also, to send a TINYINT value to a database from an application written in C, the type of the C variable should be integer. When converting a string to a TINYINT, leading and trailing spaces are removed.

Hmmm, that sounds like a bug. We handle many similar conversions. The raw IL (using OpCodes.Conv_Ovf_I4) works fine in a local test; I’m slightly hampered here, because I don’t have mysql locally, and all the servers I do have: only have unsigned tinyint. Is there any inner exception here, or something else I can work with?
