p>如果,如果出现,你正在寻求获得第一行1-100,然后行101-200,依此类推,那么你可以使用更直接(但非标准)语法。
获取101-200行:
SELECT SKIP 100 FIRST 100 t。*
FROM表AS T
WHERE ...其他条件...
您可以使用宿主变量代替字面值100(或在不同的迭代中为占位符使用不同值的单个预准备语句)。
Does informix has a function similar to the SQLServer and Oracle's row_number()
?
I have to make a query using row_number()
between
two values, but I don't know how.
This is my query in SQLServer:
SELECT col1, col2
FROM (SELECT col1, col2, ROW_NUMBER()
OVER (ORDER BY col1) AS ROWNUM FROM table) AS TB
WHERE TB.ROWNUM BETWEEN value1 AND value2
Some help?
If, as it appears, you are seeking to get first rows 1-100, then rows 101-200, and so on, then you can use a more direct (but non-standard) syntax. Other DBMS have analogous notations, handled somewhat differently.
To fetch rows 101-200:
SELECT SKIP 100 FIRST 100 t.*
FROM Table AS T
WHERE ...other criteria...
You can use a host variable in place of either literal 100 (or a single prepared statement with different values for the placeholders on different iterations).
