array(expr [, ...]) 参数 exprN:共享最不常见类型的任意类型的元素。 返回 exprNs 最不常见类型的元素的数组。 如果数组为空,或者所有元素都为 NULL,则结果类型为 NULL 类型的数组。 示例 SQL 复制 -- an array of integers > SELECT array(1, 2, 3); [1,2,3] -- an array of strings > ...
Gets the binary representation of this SqlDecimal structure as an array of integers. IsNull Indicates whether this SqlDecimal structure is null. IsPositive Indicates whether the Value of this SqlDecimal structure is greater than zero. Precision Gets the maximum number of digits used to represent...
A list or array of integers:df.iloc[[row_index1,row_index2...],[column_indexl,column_index2...] A slice object with ints:df.iloc[:,:],用:表示都取出来 A callable function with one argument: NOTE:由于iloc是基于索引(位置)的,所以遵循python索引机制,即:df.iloc[0:3,:]只会取出索引=...

The Point UDT exposes X and Y coordinates defined as integers. The UDT defines a Distance method and a GetDistanceFromXY method. The sample code retrieves the values of the primary key and UDT columns in order to demonstrate the capabilities of the UDT. The ...
默认情况下, Int64和UInit64的整型使用双引号包裹, 如果要移除双引号, 设置配置参数output_format_json_quote_64bit_integers为0。 rows_before_limit_at_least:只有查询包含LIMIT时才输出, 只有在包含group by的语句中才有意义。当查询没有LIMIT时, 执行结果的最小行数。
Assume that the T2 table has 2 columns, C1 is a SMALL INTEGER column, and C2 is an INTEGER column. The following statement inserts 10 rows of data into the T2 table. The values to be inserted are provided in host-variable arrays :hva1 (an array of INTEGERS) and :hva2 (an array of...
In this case, the string1can be converted to the integer value1, so thisSELECTstatement returns the value2. The+operator becomes addition rather than concatenation when the data types provided are integers. Data type conversion behaviors
