Erstellt eine JavaScript Date Instanz, die einen einzelnen Moment der Zeit repräsentiert. Die Definition von 'Date' in dieser Spezifikation. Standard. The date and time data types datetime, duration, and calendarDuration support efficient computations, comparisons, and formatted display of dates and times. MySQL retrieves values for a given date or time type in a standard output format, but it attempts to interpret a variety of formats for input values that you supply.

Online dating tools are an alternate way to meet potential dates. The average duration of courtship before proceeding to engagement or marriage varies considerably throughout the world. Shanghai marriage market Patterns of dating are changing in China, with increased modernization bumping into traditional ways. One report in China Daily suggests that dating for Chinese university women is "difficult" and "takes work" and steals time away from academic advancement, and places women in a precarious position of having to balance personal success against traditional Chinese relationships.

But in China, we study together. Like other women in my social circle, I have certain demands for a potential mate. He doesn't have to make much more than I do, but he must be doing at least as well as I am, and has to be compatible with me, both morally and spiritually He should also own an apartment instead of us buying one together. Remember what Virginia Wolf [sic] said? Every woman should have a room of her own. One account suggests that the dating scene in Beijing is "sad" with particular difficulties for expatriate women hoping to find romance.

In Arabic numerals, the day looks like "", that is, "like four single people standing together", and there was speculation that it originated in the late s when college students celebrated being single with "a little self-mockery" [87] but a differing explanation dates it back to events in the Roman Empire.

Dates and Time

Jinguoyuan organized periodic matchmaking events often attended by parents. Some men postpone marriage until their financial position is more secure and use wealth to help attract women. One trend is towards exclusive matchmaking events for the 'rich and powerful'; for example, an annual June event in Wuhan with expensive entry-ticket prices for men 99, RMB lets financially secure men choose so-called bikini brides based on their beauty and education[91] and the financial exclusivity of the event was criticized by the official news outlet China Daily.

There was a report that sexual relations among middle schoolers in Guangzhou sometimes resulted in abortions.

In the cities at least, it is becoming more accepted for two people to meet and try to find if there is compatibility. Writer Lavina Melwani described a happy marriage which had been arranged by the bride's father, and noted that during the engagement, the woman was allowed to go out with him before they were married on only one occasion; the couple married and found happiness.

Until recently, Indian marriages had all the trappings of a business transaction involving two deal-making families, a hardboiled matchmaker and a vocal board of shareholders — concerned uncles and aunts.

To "apply affinity" means to convert an operand to a particular storage class if and only if the conversion is lossless and reversible. Affinity is applied to operands of a comparison operator prior to the comparison according to the following rules in the order shown: Otherwise, no affinity is applied and both operands are compared as is. The expression "a IN x, y, z, In other words, the values to the right of the IN operator the "x", "y", and "z" values in this example are considered to have no affinity, even if they happen to be column values or CAST expressions.

Since the operands are already numeric, -- the application of affinity is a no-op; no conversions occur. All -- values are compared numerically.

Then a numeric comparison occurs. Values are compared as TEXT. The cast is carried through even if it is lossy and irreversible. An operand on a mathematical operator that does not look in any way numeric and is not NULL is converted to 0 or 0.

No storage class conversions occur before the sort. Collating Sequences When SQLite compares two strings, it uses a collating sequence or collating function two words for the same thing to determine which string is greater or if the two strings are equal. SQLite has three built-in collating functions: If either operand has an explicit collating function assignment using the postfix COLLATE operatorthen the explicit collating function is used for comparison, with precedence to the collating function of the left operand.

Data Types

If either operand is a column, then the collating function of that column is used with precedence to the left operand. An operand of a comparison is considered to have an explicit collating function assignment rule 1 above if any subexpression of the operand uses the postfix COLLATE operator.

Thus, if a COLLATE operator is used anywhere in a comparision expression, the collating function defined by that operator is used for string comparison regardless of what table columns might be a part of that expression.

If two or more COLLATE operator subexpressions appear anywhere in a comparison, the left most explicit collating function is used regardless of how deeply the COLLATE operators are nested in the expression and regardless of how the expression is parenthesized.
